Experimental Frenzy

You can’t cast spells or play lands from your hand, but you may take other actions with those cards (such as discarding them to activate their cycling or bloodrush abilities).

You’ll still pay all costs for a spell you cast from your library, including additional costs. You may also pay alternative costs.

Experimental Frenzy 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.
