- nontoken creatures that leave — blink, sacrifice, bounce (each makes a Mutagen)
The Splinter, the Mentor deck plan
The roles the Forge fills for this commander, and how many cards of each.
- 16× A permanent that does something every turn it is on the battlefield — the deck's body, for a commander whose text asks for nothing specific
- 7× Actually remove one problem permanent — preventing its damage is not removing it
- 10× Find the exact card the plan needs
- 3× Answer a whole board at once
- 9× Refill your hand
- 3× Keep a permanent you control alive through removal
- 11× Get ahead on mana
- 8× Make creature tokens — a static anthem or a go-wide commander needs a board to be wide
- 8× Exile a permanent you control and return it — the button a value-ETB deck presses
