Tak-Thra, Unseen Soldier

Reach, double strike
Disguise {r}{r}{b}
When Tak-Thra is turned face up, deal
damage to any target equal to Tak-Thra's
power. If a creature or planeswalker who has an ability on the stack dies from this, that ability no
longer resolves. You may then return Tak-Thra
to your hand.
