After a few easy battles, Chromaggus took awhile longer. He has a solid dragon-based deck, but that in itself is not OP. He also starts with 60 health, which is a bit unfair, but there seems to be a bug where he always plays Alexstrasza when you are below 15 and actually heals you! What’s unfair is that every turn he adds a card into your hand that benefits him, either his spells/minions cost 3 less, or heals him for 6, or deals you 3 damage, or gives him double of each card he draws. These cards take 3 mana to get rid of so in essence you are always 3 mana behind against a strong deck.

It took me many battles (~50) but I finally beat him with a mill deck. It is by no means better than Chromaggus so it requires some luck to play into the right conditions to win. Here’s the decklist:

  • Earthen Scales
  • Jade Idol
  • 2x Mistress of Mixtures
  • 2x Naturalize
  • 2x Zombie Chow
  • 2x Stubborn Gastropod
  • 2x Youthful Brewmaster
  • Brann Bronzebeard
  • 2x Coldlight Oracle
  • 2x Dancing Swords
  • 2x Deathlord
  • 2x Emperor Cobra
  • 2x Feral Rage
  • 2x Goblin Sapper
  • 2x Grove Tender
  • 2x Poison Seeds
  • Deathwing

In the early game, play the Zombie Chows, Mistresses, and Gastropods to take out the low level minions. Then start milling. Earthen Scales (with Goblin Sapper) and the Feral Rages are to heal 25 (plus whatever you get from Alex). Poison Seeds and Deathwing are the only board clears, and I found I needed all of them because I couldn’t catch up to the strong dragon board. The timing of Deathwing is also important as it allows you to get rid of all of his hero power cards in one go. In my winning game, I got it at the end (he was in fatigue) and I had been holding several double/healing cards since his hand was stuck at 10 cards – it ended up killing Alex and Ysera (Onyxia was done in by poison seeds). Finally, the one Jade Idol is to help you grow your deck and prevent milling yourself.

If you can survive his deck, then it’s an easy win!
