Butcher's Glee

Three effects bundled into one combat trick: a power boost, lifelink for the turn, and a regeneration shield. The third clause is what reshapes the bluffing math. Most pump trickery is a coin flip against open mana, the attacker betting the defender does not have removal or a bigger blocker waiting. Adding regeneration flips that bet: cast this on a creature caught in a lethal block and the shield absorbs the combat damage, so the body walks away while still connecting hard enough that the lifelink drain matters. The catch is that a regeneration shield is a single-use screen against one destruction event, not a blanket protection for the turn. It stops the block that would otherwise kill your creature, but it does not stack, and it does not answer everything: a destroy-and-can't-be-regenerated line, an exile effect, or a toughness-shrinking minus-X/minus-X all slide right past it, since none of those trip a regeneration replacement. So the security is narrower than it reads, and an opponent holding the right answer plays around it cleanly. What the card does deliver reliably is turning a favorable-looking block into a blowout and padding the caster's life on the way through. The cost of cramming three riders into one instant is that no single piece is large: the power bump is modest, the lifelink is transient, and the shield is a one-shot. Reliable in the specific window it was built for, blank against the answers it cannot see coming.
