I just beat Chapter 5! (Normal mode)
I was using George the Paladin, with his dragon-deck starter option. I chose the “give a minion Divine Shield” Hero Power.
I got the passives of “all minions have Rush” and “enemy minions cost 1 more.”
For my buckets, I mostly leaned into dragons, though once I picked a Mech option with Zilliax.
The best dragon I had was one whose attack doubles at the start of my turn. During the bartender sessions, I got to shuffle more copies of it into my deck and to buff one of them.
I’m saving the golden pack to open after work tonight.
