Tier 6: Ghastcoiler, Goldrinn, Maexxna, Hamuul

 

Gameplay:

Early game:

First round: Get Alleycat, Hyena (otherwise take the best one of the 3 you can choose from, preferably something that help you later, for example reduce cost of upgrade or get bloodgem etc.)

Second round: If you don't get any beast here, you upgrade. Otherwise buy the beast (freeze if you get more than one beast).

Third round+: Continue with the same way, if you get a beast, preferably one of the ones in the list above, then buy it. Else upgrade. You want to reach 5 star as soon as possible. Always buy Macaw if you find it. You want to have as many Macaw as possible.

When getting 5 stars: Here you want to get Mama Bear, that will help you to buff all other minions. At this stage the goal is Mama Bear + Deathrattle minions. You also want to get Rattler to give another minion reborn. It's the Macaw you want to give reborn.

6 stars (End game): You want Macaws to the left, as many as you can get, then as many Goldrinn you can get, after that it doesn't really matter what you have but Maexxna is a good one. To the right you want as many Barons as possible. You want to have reborn on all minions if possible, the first one you should prioritize is the Macaw, after that Goldrinn, 

To summarize: 

Early game; Survive

Mid game; Deathrattle + Mama Bear

End game; Trigger Goldrinn as much as possible and win!
