What a Rin and Seri, Inseparable deck wants
The plan the Forge derives for this commander: the roles it fills and how many of each.
- 8× Put haste on the commander the turn it resolves — a tap ability is unusable otherwise
- 5× Untap the commander so the tap ability is an engine, not a one-shot
- 26× A body of the exact type the commander's trigger requires — the wrong type is worthless here regardless of quality
- 6× A card that is CAST to trigger the commander — reanimating or blinking it does not count
- 4× A team pump that actually pumps tokens
- 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
