Otaimo, of Vengeful Woe

Deathtouch, double strike, haste, indestructible
Whenever a source an opponent controls causes
you to lose life, you may pay {w}{w}{b}{b}{r}{r}. If
you do, choose deathtouch, first strike, or indestructible. Creatures you control have the
chosen ability until the end of your next turn.
(Damage causes loss of life.)
With his boundless wrath, seeking death as your
sentence, your judgement awaits.
