The goal of this deck is to lethal the opponent using Depth Charge!

First, we need to assemble three Depth Charge. We can do this by playing 1 along with Brann and Zola.

Then, we need the opponent to have 6 open minion slots.

Finally, we play Holomancer, Treachery Holomancer, Wrathguard, Treachery Wrathguard, Depth Charge, Depth Charge, Depth Charge!

The two Wrathguards will take 15 each for 30 damage total!

We also definitely need some Emperor ticks. You don't actually need Drakkari if you have the full combo in hand, but it can help if Zola/Brann are on the bottom of the deck delaying the triple Depth Charge.

Extremely challenging!

Good luck!
