Chromaggus only keep if u go first since normally it will stick.
Naga is the MVP of the deck. I wouldn’t change the spells of the deck either.
Creatures you should keep on the deck:
Naga – because you can play a 5/5 and a big minion on the same turn
Alexstrasza – 15 dmg and can contest anything on board
Chromaggus – draw 2 big minions
Sylvanas – steal a big minion and they cant kill their minion when they attack her
Rafaam – always take the zombies
icehowl- normally can trade with 2 big minions
sea kraken – to kill low health minions
Any other minions you can change for any big minion you like the most. Keep in mind to leave 6-7 cost minion that you can cast at same time that one of your low cost spells.
