What it does
Evoke gives a creature an alternative casting cost—usually cheaper—but when it enters the battlefield, you must sacrifice it. This lets you pay the evoke cost instead of the normal mana cost to get the creature's enter-the-battlefield (ETB) effect quickly and cheaply, at the price of losing the body almost immediately.
The key nuance: evoke doesn't skip or replace the ETB trigger—both the ETB ability and the sacrifice trigger go on the stack together, and you choose the order. The ETB effect still happens fully. Also, you're not forced to sacrifice in response to the trigger; if the creature leaves before the sacrifice resolves, that's fine. You can also save it with effects that prevent sacrifice, though that's niche.
In Commander, evoke shines for value: cast Mulldrifter for cards, or pair evoked creatures (like Solitude or Fury) with reanimation or blink effects to dodge the sacrifice and keep the body permanently.
