What a The Sixth Doctor deck wants
The plan the Forge derives for this commander: the roles it fills and how many of each.
- 15× A permanent whose value is in its enter-the-battlefield trigger — the payload a blink deck reuses
- 24× A card that is CAST to trigger the commander — reanimating or blinking it does not count
- 5× Actually remove one problem permanent — preventing its damage is not removing it
- 1× Answer a whole board at once
- 2× Answer a spell or ability before it resolves
- 9× Find the exact card the plan needs
- 7× Refill your hand
- 2× Keep a permanent you control alive through removal
- 11× Get ahead on mana
