Intimidator Initiate

The effect of taxing a single blocker out of combat usually shows up as a one-shot instant, where you pay once to clear the way for one swing. Stapling it to a persistent trigger changes the math entirely: an all-red deck pays a small toll on spells it was already casting, and every burn spell, cheap creature, or cantrip becomes another chance to keep the one defender that matters from declaring as a blocker. The cost is low enough that a fast hand can pay the trigger two or three times in a turn, peeling away successive blockers ahead of an alpha strike. The body is incidental; this is a one-mana Shaman whose job is to convert a critical mass of red spells into reach, turning a stalled board into lethal by removing chump blockers from the combat step without ever touching them otherwise. The trigger is wider than it first reads: it keys off any player casting a red spell, opponents included, but the payment and the target both belong to you, so the engine scales with how mono-red the spell count gets across the table. Note the distinction that does the strategic work: this does not make your attacker unblockable, and it does not remove the creature. The blocker survives and is back next turn; it is simply absent from this combat. Left unanswered, the same one-mana investment does that work turn after turn, which is more than any single tempo trick can promise.
