Springans Blast!

If you control a "Springans" monster: Choose 1 opponent's Main Monster Zone; if a monster is face-up in that zone, during this turn, it cannot attack directly, also its effects are negated. If no monster is in that zone, it cannot be used this turn. If you control a Fusion Monster that lists "Fallen of Albaz" as material, you can choose 2 zones instead. You can only activate 1 "Springans Blast!" per turn.
