MTG Master Guide — Mana Base & Opening Hand Intelligence

By MTG Master EditorialPublished Mar 30, 2026Updated Oct 4, 20269 min read

Mana is the hidden engine of every Commander deck.

A mana base can look acceptable on paper and still lose games before your real plan ever starts.

MTG Master counts the colors your sources can provide and simulates early mana development. It helps you identify late colors, slow starts, and opening hands that struggle under the selected keep strategy.

This guide walks through every mana-focused layer in MTG Master so you can move from instinct to diagnosis. Instead of asking only “Do I have enough lands?”, you can ask sharper Commander questions: “Which color is really under pressure?”, “Which benchmark is missing?”, and “What swap gives me the cleanest first upgrade?”

Check whether your mana base supports your deck

MTG Master reviews color access, mana sources, ramp timing, commander castability, and opening hand reliability.

Analyze my mana base

What the Mana System Is Really Measuring

Read these three measures together when reviewing your mana base:

Capabilities: how many cards can provide each color, including conditional sources
Readiness: how often simulated early turns have usable mana and colors
Demand: which colored costs your spells ask you to pay, and when

Read these measures together. A source count is not an amount of mana available now, and a simulated access rate is not a guarantee that every spell can be cast.

1. Mana Base Analysis: the benchmark and alignment view

The Mana Base area is the first place to look when you want to know whether your deck can function on curve and in the right colors.

It evaluates things like:

How reliably you can produce untapped colored mana early
Whether your commander colors arrive on time
How your mana production lines up with real spell demand
Which parts of the mana base add hidden stress

Think of this as the structural view of your mana. It is less about one flashy opener and more about whether the shell is coherent enough to support the games you want to play.

2. Color sources & access: full credit for each color

The full-width color panel shows an independent source count and turn-one and turn-three access estimates for each color. Desktop displays the colors in a row; mobile stacks them.

How to read each color card

Sources count fully for every color they can provide. Underground Sea is one blue source and one black source; it is not half of each. The same principle applies to multicolor rocks, creatures, and other mana sources.
An ordinary dual land still produces only one mana per tap. It can pay U or B, but cannot pay UB or BB by itself. Sources that genuinely produce multiple mana use their actual output.
Replacing Underground Sea with a Swamp keeps the black source count unchanged and removes a blue source. A land entering tapped can still offer worse early access than an untapped basic.
Counts include conditional capabilities. Simulated access applies supported entry conditions, activation costs, chosen colors, and spending restrictions. Check confidence notes for unsupported effects.

Percentages have different meanings

Color access estimates the chance of being able to produce one mana of that color in the modeled turn. Each color is measured separately; the percentages do not add up to 100%.
Access to blue and black separately does not mean both can be paid together. Use simultaneous-color and repeated-pip benchmarks for that question.
Weighted pip demand describes that color’s share of the deck’s weighted colored costs. It is not a target percentage of sources and is not subtracted from access rates.
Each color is tested through its own legal land and ramp choices using the same kept hands and draws. With Plains and Forest in hand, either color can be available on turn one, even though you cannot pay both together. The displayed miss rate is the share of sampled hands where the search did not find usable mana of that color. The sample size appears under “How to read these estimates”; 100% in a sample is not a guarantee.

Color sources and independent turn-one and turn-three access estimates in MTG Master — Example from a test deck. Source counts describe capabilities; simulation percentages vary with the deck and settings.

The notes also separate colorless-only lands from sources that offer both colored and colorless mana. Generic costs can use either when spending restrictions allow it; explicit colorless costs need colorless mana.

3. Early mana readiness and the demand timeline

The compact readiness panel sits below the color cards. Its score is the lowest measured early-readiness percentage, with highlights, warnings, and recommendations alongside it.

The score uses these checks when measured

Two mana by turn two
Three mana by turn three
Access to each demanded color individually by turn three
Payment of the selected early repeated-pip spell’s entire cost by turn three, when a target exists

What the score does not mean

It is a conservative summary of the measured checks, not the chance of casting every spell or winning a game.
Missing estimates stay unmeasured instead of becoming zero. A high score cannot certify effects the simulation does not model.
Color-access warnings identify turn-three estimates below 90% or below 75%. They are review prompts, not a prescribed number of lands to add.

Early Turn Stress is a demand timeline

Bars group weighted colored and explicit colorless requirements by mana-value turn bucket.
The timeline describes where costs cluster; it does not simulate drawing or casting those spells. Generic costs are not displayed as colorless requirements.

Use the score to locate an early check worth reviewing, then inspect the relevant color, spell cost, and source conditions.

4. Benchmarks: separate access from simultaneous payment

Each benchmark asks a specific question about the simulated mana sequence. Read its label and target before comparing percentages.

Key checks

Turn-one live color: access to untapped mana in a deck color. The individual color cards show which colors are available.
Two mana by turn two and three mana by turn three: early mana development.
All colors by turn three: paying one mana of every deck color together. One dual land cannot satisfy two of those payments at once.
Repeated pips by turn three: paying the selected spell’s full cost, including its actual number of repeated colored symbols. This is not a test of every double-pip spell in the deck.
Commander timing: paying the modeled commander cost with mana left after the chosen actions. Installed mana capacity and mana remaining to cast a spell can differ.

Analyze my opening hands

5. Opening Hand Analysis: simulation instead of guesswork

Opening Hand Analysis simulates draws, mulligans, land plays, and supported mana actions. It uses the same sequencing rules as Mana Base and includes the same independent color-source and access display.

This layer measures things like:

Opening Consistency Score
Keep on 7 rate
Ideal land hands after mulligans
Commander by Turn 4 probability
Land distribution, mulligan patterns, and early mana development

Opening hand analysis overview in MTG Master

Use the same simulation count, mulligan mode, and keep strategy when comparing lists. Mana Base uses 100 scenarios with balanced London mulligans. Small changes can reflect sampling and sequencing choices; more runs reduce sampling noise but do not remove model limitations. Confidence notes describe assumptions, including no opposing removal and unsupported effects.

6. Why hands struggle: reading the failure indicators

The failure view flags patterns in simulated hands, such as too few lands or delayed ramp. These indicators help you investigate a missed benchmark; they do not prove a single cause.

Common failure causes include:

Tapped-land tempo slowing your first real turn
Missing early color even when total mana is technically fine
Low-land keeps or clunky development patterns
Hands with enough mana, but in the wrong colors

Opening hand failure analysis in MTG Master

Several indicators can apply to the same hand, so their percentages need not add up to 100%. Review them alongside the relevant benchmark and the cards in your list.

7. Premium Mana Fix Plan: from diagnosis to action

Once the deck has shown you where it is stumbling, the Fix Plan turns that signal into concrete upgrades and cuts.

The Fix Plan is built around:

Collection-aware upgrades
Preferred swaps with Add / Cut actions
Benchmark-linked priorities tied to real weaknesses
Fix candidate modes: collection first, collection only, or any card

Typical recommendations include:

Replacing slow taplands with untapped colored sources
Reducing low-impact colorless utility lands
Rebalancing a strained color without hurting the rest of the base
Improving early development before adding speculative ramp

Review each suggested Add / Cut before applying it, then rerun the analysis. A proposed swap is a starting point for testing, not a guaranteed improvement. Check the current in-app credit cost before requesting a plan.

8. Recommended workflow: how to use the full mana system

The strongest way to use these tools is as a sequence, not as isolated widgets.

A strong workflow looks like this:

Start with full source counts and individual color access, then inspect the early readiness score and its weakest measured check
Review benchmarks to see which early turns are failing
Run Opening Hand Analysis to confirm how those issues show up in kept hands
Read the failure indicators to identify cards and sequencing worth testing
Apply the Fix Plan and re-test the deck

That turns the mana suite into a full loop: diagnosis, understanding, action, and validation.

9. Core principles MTG Master follows for mana

The platform is built on a few practical truths that matter much more than generic mana advice.

The big ones are:

A multicolor source counts fully for each available color, but cannot spend the same mana twice
Source capabilities, available mana, and spell castability are different measurements
Tapped entry, activation inputs, and restrictions can matter as much as color coverage
Independent color percentages are not shares of a single whole
Simulations estimate supported play patterns; confidence notes and actual playtesting still matter

Put more bluntly: a land that produces the right color too late often plays like it never produced it at all.

Final takeaway

Start with the colors your sources can provide, then check whether your early turns can use them.

Review individual color access alongside simultaneous payments and actual spell targets. Do not replace a flexible dual with a basic merely to improve a relative color percentage.

Change the deck deliberately, rerun the same settings, and use the results together with playtesting.
