Flourishing Frolic

Excavate cards from your Deck equal to the number of "Flourishing Frolic" in your GY + 3, and if you excavate at least 1 Monster, 1 Spell, and 1 Trap, add 1 of them to your hand and send the other cards to the GY. If you did not, shuffle all excavated cards into your Deck. You can only activate 1 "Flourishing Frolic" per turn.
