When your commander deals combat damage to a player, if there is no monarch, you become the monarch. At the beginning of the monarch's end step, that player draws a card.

If an opponent would mill one or more cards, they mill twice that many cards instead. (To mill a card, a player puts the top card of their library into their graveyard.)

As Council of the Absolute enters the battlefield, choose a noncreature, nonland card name. Your opponents can't cast spells with the chosen name. Spells with the chosen name you cast cost {2} less to cast.

Glistener Seer enters the battlefield with three oil counters on it. {T}, Remove an oil counter from Glistener Seer: Scry 1. (Look at the top card of your library. You may put that card on the bottom.)

White spells you cast cost {1} less to cast. Blue spells you cast cost {1} less to cast. Spells your opponents cast cost {1} more to cast.

Flash Tapped creatures you control can block as though they were untapped.

Changeling (This card is every creature type.) {X}: Until end of turn, creatures you control have base power and toughness X/X and gain all creature types.

Lifelink (Damage dealt by this creature also causes you to gain that much life.) If you would gain life, you gain twice that much life instead.
