'Zendikar' cards

Players may cast enchantment spells as though they had flash. Whenever chaos ensues, destroy target creature that isn't enchanted.

Creatures with power 7 or greater can't attack or block. Whenever chaos ensues, create a 7/7 colorless Eldrazi creature token with annihilator 1. (Whenever it attacks, defending player sacrifices a permanent of their choice.)

Whenever a nontoken creature enters, its controller may search their library for a basic land card, put it onto the battlefield tapped, then shuffle. Whenever chaos ensues, target land becomes a 4/4 creature that's still a land.

Creatures can't block. Whenever chaos ensues, draw a card for each land you control.
