Gandalf's Sanction

Spell-count payoffs usually cash out into card advantage or a scaling body; this one funnels the count straight into face damage. The X here is your graveyard's instant and sorcery cards, and the excess-damage clause is what turns a removal spell into a finisher: point it at a small creature the opponent must not lose, and everything past that creature's toughness rolls over into their life total. That reframes the targeting decision entirely. You are not choosing the biggest threat to kill; you are choosing the cheapest legal target that lets the most damage spill through, which means a lone token or a one-toughness dork is often the ideal recipient. The reward compounds the same way a spellslinger graveyard does: the more you have already cast, the more this closes. It sits in a lineage of graveyard-as-fuel finishers that reward a full bin of spent spells, but where most of those threaten to loop or recur, this one simply converts the archive into a lethal number. The friction is that it does nothing early and asks for a creature to exist at all; a wide-open board offers no vessel for the overflow. Line it up correctly, though, and a mid-game removal spell becomes the last thing you cast.
