Light Barrier (LODT-EN051) - Light of Destruction 1st Edition

During your Standby Phase, toss a coin. If the result is Tails, the following effects are negated until your next Standby Phase: When you Summon an "Arcana Force" monster, choose which effect to apply without tossing a coin. If an "Arcana Force" monster destroys an opponent's monster by battle, you gain Life Points equal to the destroyed monster's original ATK.
