Selfless Glyphweaver // Deadly Vanity

Two answers to the same question, folded into one card: how do I not die to a wrath, and how do I turn a wrath into a win. The front is a durable Cleric whose only trick is a self-exile that grants your creatures indestructible until end of turn; held up as a response to a sweeper on the stack, it blanks the board wipe before it ever resolves. The back is that sweeper itself: destroy every creature and planeswalker except one of your choosing. What sharpens the pairing is that both halves attack the same board-clearing problem from opposite ends, the shield on one face and the hammer on the other. The exile clause is the discipline on the front: the protection is a genuine one-shot, so the creature cannot camp on the battlefield rationing out indestructible turn after turn the way a static enabler could. It spends its own body to buy a single window, activated in response to the threat rather than at leisure. Deadly Vanity is expensive and blunt by design, a sorcery-speed reset that leaves you the keeper and everyone else nothing; the "choose, then destroy all others" template even lets it spare a creature you do not control, though the natural line is to protect your own bomb. Read together, this is one flexible slot that plays defense while you are behind and closes the board when you are ahead, and the game tells you which face to cast.
