Legendary Creature — Frog
Whenever a Frog you control attacks, mill three cards. Whenever a permanent card is put into your graveyard from your library, exile it with a croak counter on it. You may play lands and cast spells from among cards you own in exile with croak counters on them.
“Mill into exile to build a hand—attack with Frogs to fill your graveyard.”
Grolnok is a self-mill commander that turns your graveyard into a second hand. Every time your Frogs attack, you mill three cards, loading your graveyard with lands and spells you can cast from exile. The key is that any permanent milled this way gets exiled with a croak counter, becoming playable on your terms—essentially giving you repeatable value from cards that would normally be wasted. You're not trying to win through mill damage; instead, you're fueling a graveyard-to-exile engine that generates card advantage and mana acceleration.
Build around having multiple Frogs attacking each turn and ways to make those attacks happen reliably. Green gives you ramp and creature generators, while blue provides card draw and bounce effects to protect Grolnok or reset the board. Your win condition is typically combat damage—you're swinging with growing Frog tokens and buffed creatures while simultaneously filling your exile zone with gas to cast the best cards you mill. Think of it as a midrange strategy with built-in card advantage that snowballs over several turns.
