The goal of this Standard Druid OTK combo deck is to use Witching Hour to summon Druid of the Claw and then Savage Roar to victory!

We do this by having Druid of Claw die at some point during the game.

Then, we need to gather two coins from Licensed Adventurer (Alternatively 2 Innervate).

We also need to use Dreampetal Florist to discount a Gloop Sprayer to 0 mana.

Finally, we play Witching Hour, Witching Hour, Gloop Sprayer between the two Druid of the Claw, Savage Roar, Coin, Coin, Savage Roar!

Very challenging! Good luck!
