Defabricate

Permission that trades away breadth for two kinds of surgery. Aim it at an artifact or enchantment spell and the exile rider does the real work: the spell never touches the graveyard, so any recursion loop that would replay it goes cold. Countering a spell already keeps it off the battlefield, so it was never going to trigger its own dies-effects; the exile clause is aimed one step further back, at decks built to rebuy their countered threats from the yard. That distinction is the difference between a counter that answers the spell in front of you and one that removes it from the game. The other choice is the rarer trick in blue's toolkit: countering an activated or triggered ability. Most permission only ever sees spells on the stack, but plenty of games hinge on an ability instead. A planeswalker loyalty activation, an equip that swings combat, a triggered value engine, a combo piece's payoff trigger: fizzle the ability and the enabler stays on the board doing nothing, a window a straight spell-counter never had. The one activation it cannot touch is a mana ability, which resolves without using the stack and cannot be targeted at all. The cost of this focus is plain: it does nothing to a creature spell or a burn spell, and against an opponent light on artifacts, enchantments, and stack-using abilities it is a blank. This is permission tuned for a specific opponent rather than a catch-all.
