The gameplan of the deck is in the name. Just use Touch of Battle
to give Black-Sky Harbinger
Deadly and wipe the opponent's board. As backup deadly targets there are Stormcaller
for the memes and Yetipult
for more card draw. The rest of the deck is mostly there to stabilize the early game and get us to Harbinger power.
I am not so sure about all the card choices as I'm mostly working with what I have in my collection, but after throwing this together I went 4-0 in master gauntlets. So I probably did something right.
