Legendary Planeswalker — Jace
At the beginning of combat on each opponent's turn, they may pay 
. If they don't, creatures they control can't attack Jaces you control this turn.
+1: Draw two cards, then put a card from your hand on the bottom of your library.
−3: Exile another target planeswalker or creature you control. Reveal cards from the top of your library until you reveal a creature or planeswalker card. Put that card onto the battlefield and the rest on the bottom of your library in a random order.

Overview
- Jace provides steady card selection with a +1 that draws two before putting a card back on the bottom of your library.
- His combat trigger discourages opponents from attacking your Jaces unless they spend mana, buying time for a planeswalker-focused board.
- The -3 converts another creature or planeswalker into the first creature or planeswalker found from the top of your library, rewarding careful deck construction and topdeck setup.
- Games often revolve around resolving Jace, protecting him through a full turn cycle, then leveraging repeated filtering or a timely -3 into a major battlefield upgrade.
- With only one public deck in the snapshot, available card signals are examples rather than an established shell.
Common lines
- Deploy Jace once you can reasonably defend him, then use the +1 to improve card quality while advancing toward another loyalty activation.
- Use expendable creatures or lower-impact planeswalkers as fodder for the -3 when a higher-impact reveal can swing the board.
- Shape the top of the library before activating the -3 when possible, making the transformation effect more reliable.
- Pressure opponents to spend mana during combat if they want to attack your planeswalkers, then use that tempo window to develop further.
Strengths
- Four-color identity supports broad access to interaction, protection, threats, and planeswalkers.
- The +1 generates immediate card flow while smoothing future draws.
- Combat taxation can make attacking Jace costly, especially when opponents need mana for development or interaction.
- The -3 can cheat a creature or planeswalker directly onto the battlefield without paying its mana cost.
- Jace's ability to be your commander gives a planeswalker-centered strategy reliable access to its engine piece.
Weaknesses
- Jace costs five mana and requires all four colors, so early mana development matters.
- The -3 is inherently uncertain without ways to manage the top of the library.
- Jace can still be removed directly, and the combat trigger only protects Jaces from attacks rather than other forms of interaction.
- Repeated use of the -3 consumes your own board, so the deck needs suitable permanents to exchange.
- A board built around expensive hits can be vulnerable if Jace is removed before an activation pays off.
Rule zero notes
- Discuss any land-destruction effects before the game; the lone deck snapshot includes Armageddon and Boom // Bust as examples.
- Disclose whether the deck uses fast mana rituals, tutors, or free interaction; the lone snapshot includes examples of each.
- Let the table know if the deck is built to cheat unusually large creatures or planeswalkers into play with Jace's -3.
- If running oppressive battlefield threats or resource denial, clarify whether those effects are part of the deck's primary plan.
- Because there is only one public deck in the snapshot, align power expectations through a direct pregame conversation rather than assuming a standard build.
Matchups
Best into
- Creature-heavy midrange pods that rely on combat to pressure planeswalkers.
- Slower value decks that give Jace time to generate selection and set up a transformation turn.
- Tables where opponents frequently tap low, making the attack tax more meaningful.
Struggles against
- Fast combo tables that can win without needing combat.
- Interaction-heavy pods that can remove Jace before he generates value.
- Aggressive decks that can pressure both Jace and your life total while retaining mana to pay the attack tax.
- Strategies that easily punish expensive permanents or exploit a tapped-out five-mana commander turn.
FAQ
What is Jace's main role in the deck?
Jace is a card-selection engine and a battlefield-conversion tool. His +1 improves your hand, while his -3 can exchange a lesser permanent for a new creature or planeswalker from the library.
Does Jace protect himself?
Partially. At the beginning of each opponent's combat, that opponent must pay mana if they want their creatures to attack Jaces you control that turn.
How does the -3 choose what enters the battlefield?
You exile another creature or planeswalker you control, then reveal from the top until you reveal a creature or planeswalker card. That revealed card enters the battlefield, so library composition and topdeck control matter.
Can Jace's -3 find another planeswalker?
Yes. The ability can reveal either a creature card or a planeswalker card, and either type can enter the battlefield.
What kind of finish does Jace support?
He can support wins through a superior board of creatures and planeswalkers, particularly after converting a small permanent into a high-impact threat. The single available deck signal also includes examples of large threats and disruptive spells, but it is not enough to define a standard closing package.
