The Master, Gallifrey's End

Legendary Creature — Time Lord Rogue

Make Them Pay — Whenever a nontoken artifact creature you control dies, you may exile it. If you do, choose an opponent with the most life among your opponents. That player faces a villainous choice — They lose 4 life, or you create a token that's a copy of that card.

"A perfect army, right? Right? Oh, come in, my pretties!"
