So after playing some more games I think this deck beats all agro decks pretty easily and has a plus matchup vs Jade Druid. Dragon Priest however 0-4 feels bad

Mulligans I think are very matchup dependant.

Generally you want your war axes and acolytes to start. I will if I am playing what I think will be a rush deck keep a Taunt card or a Bash for early removal

5-1 vs Mid Range/Jade/Pirate Shaman some variation of those
1-1 vs Mage idk OTK..?
1-0 vs Buff Paladin
2-0 vs Reno Lock
4-1 vs Pirate Warrior
2-0 vs Freeze Mage
4-0 vs Pirate Rogue
0-2 vs Dragon Priest (I HATE DRAGON PRIEST!)
0-1 vs Jade Druid ( I think Alexstaza will help vs Jade Druid to potentially combo)

I personally don’t have Ysera or N’zoth, however what I did was replace the infested Taurens x2 with Bloodhoof Braves x2, Ysera with Rag and N’zoth with Onxiya. Why Onxiya..? Cause shes big and floods the board I also don’t really have any other big legendaries that I think do better. I considered Alexstraza for the heal or burst dmg but so far I like the board rush more. As of 10 games played I’ve only faced freeze mage and Pirate decks 10-0 so far. Will update with more results
