What it does
Devour lets a creature enter the battlefield bigger by sacrificing your other creatures. As it enters, you may sacrifice any number of creatures, and it gets a number of +1/+1 counters based on those sacrifices—"Devour 2" means two counters per creature eaten, while plain "Devour" (or Devour 1) gives one each.
The key nuance: the sacrificed creatures are devoured as the Devour creature enters, so they're never on the battlefield alongside it. This matters for triggers—"whenever a creature dies" abilities will see the sacrifices, but the devouring creature isn't around yet to trigger its own "enters with creatures" type effects from them. Some Devour cards (like those making tokens) reference how many creatures were devoured.
In Commander, Devour synergizes beautifully with token swarms and aristocrats decks, turning a wide board into one huge threat while triggering death payoffs like Blood Artist along the way.
