Portal Manipulator
There is a narrow, gleeful window this creature was built to exploit: the declare attackers step, after your opponent has committed the crew but before damage is dealt. Flash a 3/2 in during that pause and you redirect their attackers wherever you like, most cruelly at another opponent, so a swing meant for you becomes a swing meant for the player across the table. The design leans on a redirection template that has quietly existed for years (effects that change a creature's attack target mid-combat), but folding it onto a flash body turns a reactive trick into a deployable threat that also reroutes the whole assault. The timing constraint is the entire cost of the effect: it does nothing outside that single step, and it does nothing if no attackers are declared, so this is a card you hold mana behind and fire on a read of the board rather than jam on your own turn. The hybrid pips keep it available to any deck that touches white or blue, which matters for a card whose ceiling is entirely political: the value it generates is measured in the goodwill you spend and the grudges you redirect, not in the 3/2 body that eventually trades away.
