Arrek, Lord of Truths and Lies

Flying, deathtouch, lifelink.

Opponents can’t gain life.

Whenever an opponent casts a spell or ability, Arrek, Lord of Truths and Lies, deals 3 damage to a target creature or player and 1 damage to each creature on the battlefield.

The truth isn’t what hurts; it’s what comes after you’ve spoken it. So, do you want to play? Or are you afraid of what you might reveal?
