Summoning Materia

The top card of your library isn't in your hand, so you can't cycle it, discard it, or activate any of its abilities that could be activated from your hand.

Summoning Materia lets you look at the top card of your library whenever you want (with one restriction—see below), even if you don't have priority. This action doesn't use the stack. Knowing what that card is becomes part of the information you have access to, just like you can look at the cards in your hand.

You must follow all normal timing rules for spells cast using the second ability and must pay all costs for spells cast this way. To cast a spell this way, you may choose to pay any alternative costs or optional additional costs the spell may have (such as a kicker cost). You must pay any mandatory additional costs.
