What a Marrow-Gnawer deck needs
Plays as rat typal. What the commander asks of the other 99 — read from the card and checked by hand.
- expendable creatures and tokens to sacrifice (the commander is a sacrifice outlet)
- rat creatures (its text counts them)
- haste and untap effects that reach the commander (a tap ability is unusable the turn it lands)
The Marrow-Gnawer deck plan
The roles the Forge fills for this commander, and how many cards 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
- 5× Creatures you are happy to sacrifice — a free sac outlet on the commander is worthless with nothing to feed it
- 4× A team pump that actually pumps tokens
- 5× Actually remove one problem permanent — preventing its damage is not removing it
- 9× Find the exact card the plan needs
- 1× Answer a whole board at once
- 7× Refill your hand
