Grisly Sigil

The whole design lives in a conditional: was the target already dealt noncombat damage this turn? Untouched, this is a single point of removal and a single point of lifegain, barely a spell. But layer it behind a ping, a fight effect, or another burn spell earlier in the turn and the payout triples to three damage and three life. It wants to be the follow-through rather than the whole answer, which is a rarer thing to build around than it sounds: most removal is priced to close a question by itself, and this one is priced to finish a question someone else opened. Casualty 1 is the multiplier that reframes it entirely, and stack order is what makes the trick self-contained. Sacrifice a creature as you cast it and you copy the spell, but that copy goes on the stack above the original, so it resolves first: the copy deals the opening 1 damage to a fresh target, marking it as having taken noncombat damage this turn, and then the original resolves into the softened target for the full 3 and the full 3 life. One spell sets up its own escalation. It is one-mana lifegain that scales with how much noncombat damage your deck is already generating, which ties it to aristocrat and pinger shells rather than to any color-pair goodstuff pile. The floor is genuinely low and the ceiling asks you to have done homework before you cast it, and that gap between the two lines is the entire point.
