Azure Beastbinder

The evasion clause and the attack trigger are two different design levers pointed at the same board, and that overlap is what makes the little Rat more than a chip-in body. A ceiling of "can't be blocked by power 2 or greater" means it slips past the fatties and gets stopped by tokens and utility dorks, so it wants to trade its combat step for the trigger rather than for damage. That trigger is where the real work happens: stripping abilities from an artifact, creature, or planeswalker turns off a mana rock, a keyword-heavy blocker, a Planeswalker's static loyalty defenses, or a creature's death payoff, all at instant-relevant timing since it fires on the declare-attackers step and lasts until your next turn. On a creature it goes further, flattening the target to 2/2, which is enough to make the Beastbinder's own evasion condition kick in against it or shrink a threat into range of the rest of your team. The catch is that everything resets on your untap, so the lock is rented rather than owned; you are buying a single turn cycle of a neutered permanent, and you pay for it by committing to the attack every turn. It reads as a tempo creature, but the design is really a repeatable, attack-gated Song of the Dryads that trades permanence for reach.
