A board of Khadgar, Baron, Eliza and a few of the tier 1 Pirate that summons a 1/1 Pirate that attacks immediately can get out of here now any day. Huge minions in the way too early mid game. It's WAAAAY too easy to put together. Needs nerfed asap.
Having 2xKhadgar, 1xBaron and 1xEliza already results in +16/+8 for each onedrop that dies, with plenty of damage from the tokens.
One weakness of this build is that you cannot naturally transition to it, like you used to do with Beasts back when Goldrin was a 5*. The other is that there are easy counters to it. Buy a small taunt so their buffed token won't die and their loop will stop. Or find a Zapp.
