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).

If the top card of your library changes while you’re casting a spell, playing a land, or activating an ability, you can’t look at the new top card until you finish doing so. This means that if you cast the top card of your library, you can’t look at the next one until you’re done paying for that spell.

You must follow the normal timing permissions and restrictions of the cards you play from your library.
