You definatly want to try and pick up roll the bones, since you can get good card draw early on
Same with Thalnos and loot hoarder
Try to build a board of 2-3 minions and drop your Spawn for the buff
This deck is a random one that I created for fun, and it got me to Rank 10. It revolves around 3 core cards, Leeroy,Onyx Spellstone, and Nzoth.
You want the leeroy for the ending game damage to finsih off the game
You want the Onyx Spellstone to makee sure the enemy can’t have that big of a board
And N'Zoth, The Corruptor for making a giant board
