What an Uldaros Theorix deck needs

Plays as ETB value. What the commander asks of the other 99 — read from the card and checked by hand.

• spells at or below its mana-value cap (it casts them free; under the cap the cheap ones hit too)
• blink and recursion aimed at the commander itself (its value is its own enter trigger)
• self-mill, discard and recursion (the graveyard is a resource its text reads)

The Uldaros Theorix deck plan

The roles the Forge fills for this commander, and how many cards of each.

• 10× Exile a permanent you control and return it — the button a value-ETB deck presses
• 8× Evasion that does NOT target or attach — for a commander your own auras and equipment cannot legally touch
• 11× A permanent whose value is in its enter-the-battlefield trigger — the payload a blink deck reuses
• 10× Put your own cards into your graveyard as a resource
• 5× Actually remove one problem permanent — preventing its damage is not removing it
• 9× Find the exact card the plan needs
• 2× Answer a spell or ability before it resolves
• 1× Answer a whole board at once
• 7× Refill your hand

Best cards for Uldaros Theorix

Ranked by an engine that reads what each card does — its real cost, its delay and how reliably it works — rather than counting how often other people play it.
