What a Karumonix, the Rat King deck wants
The plan the Forge derives for this commander: the roles it fills and how many of each.
- 6× Exile a permanent you control and return it — the button a value-ETB deck presses
- 16× A creature that HAS the keyword the commander's trigger counts — a card that merely says the word is not one
- 26× A body of the exact type the commander's trigger requires — the wrong type is worthless here regardless of quality
- 8× A permanent whose value is in its enter-the-battlefield trigger — the payload a blink deck reuses
- 5× Actually remove one problem permanent — preventing its damage is not removing it
- 1× Answer a whole board at once
- 9× Find the exact card the plan needs
- 7× Refill your hand
- 2× Keep a permanent you control alive through removal
