Exile the top card of your library. During your next turn, you may play that card.
Storm (When you cast this spell, copy it for each spell cast before it this turn.)
Playing the card has the same timing restrictions and requires the same payments as normal, but it can only be played next turn.
You can play the exiled card only on your next turn after Galvanic Relay resolves. Notably, this means you cannot play it the same turn you cast Galvanic Relay.
