Thanks to HotMEOWTH for being an inspiringly good player and unfortunately for taking the short end of the RNG.
Always keep Loot Hoarder. Keep Doomsayer against non-control decks. Consider keeping a secret if you have a good 2 drop, and keep Eaglehorn Bow on coin. Tracking is risky but a worthwhile addition. You need 5 burn spells to guarantee lethal vs a nonwarrior. Total combo is 42 damage, with emperor ticking 7 cards. Alternate wincondition is to amass bow charges and go face.
