Baruuk, The Pacifist

Flash, Defender
When Baruuk enters the battlefield, detain X permanents you don't control, when X is the
amount of damage you've taken this turn.
Whenever you lose 10 or more life in a single
turn, Baruuk loses defender and gains double
strike until end of turn. You gain 3 life for each creature you don't control that dies from combat damage this turn.
