Creatures with power greater than the number of cards in your hand can't attack.

Commander creatures you own have "Creature tokens you control get +2/+2."

Whenever a creature you control with power 2 or less attacks, it gains skulk until end of turn. (It can't be blocked by creatures with greater power.)

Whenever a creature with power 4 or greater attacks you, its controller loses 2 life and you gain 2 life.

Exile target creature. Its controller may search their library for a basic land card, put that card onto the battlefield tapped, then shuffle.

Whenever you planeswalk to Two Streams Facility and at the beginning of the first upkeep of the game, each player chooses green anchor or red waterfall.

Each player who last chose green anchor may play an additional land during each of their turns.

Creatures controlled by players who last chose red waterfall get +2/+0 and have haste.

Whenever chaos ensues, each player who last chose green anchor chooses red waterfall, and vice versa.
