Priority Avenger (CMB1-9) is a white Creature — Bird Wizard from the Mystery Booster Playtest Cards 2019 set. It has Flying and a replacement/global rule that prevents players from casting instant spells unless a spell or ability is already on the stack, changing timing interactions. As a 3/4 for four mana it serves as a flying body while enforcing an unusual timing restriction that can shape when responses and instant-speed interaction are possible.
