Valkyr Trooper

Breakout {1}{r}{w} (You may cast this card for its
breakout cost when you draw it if it's the first card
you drew this turn. If you do, it gains haste, and you sacrifice it at the beginning of the next end step.)
Flying, vigilance
When Valkyr Trooper dies, return it to its
owner's hand at the beginning of the next
end step.
