Faerie Fencing

Black's X-cost removal has always been priced honestly: pay the full mana, kill the thing. The tribal rider here rewrites that math. Control a Faerie as you cast it and the spell hands you three extra points of toughness reduction, which means the X you actually pay to answer a creature drops by three whenever the board condition is met. That turns a fair, scaling removal spell into a lopsided one: the same that trades evenly with a four-toughness threat when you have no Faeries out clears a seven-toughness body when you do. The design is careful about the timing, though. The check happens as you cast the spell, not when it resolves, so the opponent cannot fizzle the bonus by killing your Faerie in response; once it is on the stack, the extra -3/-3 is locked in. That instant-speed window is the whole appeal for a deck built around evasive flyers, since the removal doubles as a combat trick that punishes a blocker while your board of Faeries is doing its work. It is a conditional discount stapled to an ordinary kill spell, and the condition is exactly the kind of thing a dedicated tribal shell keeps satisfied without trying.
