Toss a coin and apply the appropriate effect, or, if "Light Barrier" is in your Field Zone, choose which effect to apply without tossing a coin.
● Heads: Add 1 card that has a coin tossing effect from your Deck to your hand, except "Arcana Reading".
● Tails: Your opponent adds 1 card from their Deck to their hand.
You can banish this card from your GY; immediately after this effect resolves, Normal Summon 1 "Arcana Force" monster from your hand. You can only use each effect of "Arcana Reading" once per turn.
