What a Grolnok, the Omnivore deck needs
Plays as frog typal. What the commander asks of the other 99 — read from the card and checked by hand.
- cards that exile from your own library and play from exile (its payoff fires on every card played from exile)
- self-mill, discard and recursion (the graveyard is a resource its text reads)
- frog creatures (its text counts them)
- a wide board that attacks every turn (the trigger fires on the attack)
