Master of Diversion

The trick is in the timing word: this taps a blocker on the declare-attackers step, before blockers are declared, which makes the effect read less like removal and more like a recurring, single-target Falter. Every swing strips the defending player of one potential blocker for the turn. The trigger goes on the stack and the opponent gets priority to respond before combat moves forward, but killing the Master itself no longer helps at that point: the attack trigger is already on the stack and will resolve independent of its source. The only way to save the tap is to answer the target directly (bounce it, blink it, protect it) or otherwise make it an illegal target. A 2/2 attached to that engine is a deliberately modest body in service of a repeatable enabler: the design wants the card pushing a board rather than winning a fight, clearing a path for bigger attackers while chipping in its own two points. It is most pointed against a deck leaning on one large defender, since the same creature can be tapped down attack after attack and never get to block. This is workmanlike go-wide white aggression, the kind of attack-trigger evasion enabler that rewards a wide board over a tall one, and a clean illustration of how tapping on declare-attackers does quiet structural work that an instant-speed tap spell would have to be recast every turn to match.
