LockExile all noncreature spells players cast from their handPlayers can only cast one noncreature spell per turn
How it works
Whenever a player casts a noncreature spell from their hand, Knowledge Pool triggers, exiling that spell.
Because Deafening Silence prevents players from casting more than one noncreature spell each turn, players cannot cast a noncreature spell permitted by Knowledge Pool, or any other noncreature spell that turn.
