Get ready for a wild ride.

For the combo, you need these cards in hand and have them hit by an Emperor tick: Elise, Twig, Floop, Pounce, 2 Innervate, and preferably nothing else.

Once you have organized your hand, you should play the cards in this order:

First play Elise, then Twig

You should have 3 mana remaining, and your hand should be: 2 Floops, Twig, 2 Pounce, 4 Innervate

Next play 3 Innervate, Floop

Now you have 2 mana, and your hand is 2 Floop, 2 Twig, 4 Pouce, 2 Innervate

Play both innervates, Twig, and Pounce.

Now you have the full combo of 10 mana, 2 Floop, Twig,  3 Pounce

Now play Floop, Twig, 3 Pounce repetitively until you have enough attack to destroy the hero.

Hope you previously mained APM Priest lol
