Fill your opponent's hand with Rocks. Either they play the rocks and you win because their lanes are full of junk that you can easily overcome. Or they keep the Rocks in hand and you win because of the power of Ronan. Other win conditions are Darkhawk + Mystique. Odin is there to help juice either Darkhawk or Ronan on the final turn by playing him onto Maximus, Master Mold or Rockslide.
Speaking of Master Mold, he's the namesake of this deck and does a great job of weakening your opponent's board and boosting up Ronan. You definitely want to play him sooner than later to force your opponent to start making hard decisions on what cards to play. Master Mold really punishes skipping turns.
This deck is super weak to Enchantress, Rogue, Shang Chi and Super Skrull. The first 3 are pretty obvious but Super Skrull can be really effective here because we are playing multiple Ongoing effects. Even though our deck won't have as many cards as theirs, their Super Skrull will copy both instances of the same Ongoing (aka the original card and the Mystique copy) which will probably allow him to overpower us. We are also weak to high power cards like Shuri's Red SKull and we don't have any tech cards.
This deck is probably weak due to the aforementioned lack of tech cards. They are so powerful that you want to be running some of them in most decks. I think Cosmo could have a place here despite providing some anti-synergy with Master Mold. He saves us from all the scary counters to Ongoings that I mentioned. In that case he'd make your Ronan weaker because they could get rid of the sentinels, BUT they would have also played two sentinels to your Cosmo lane so you can probably over power them with a card like Darkhawk anyway. Also, if you play a turn 6 Odin onto Master Mold then that can be a way to still juice up Ronan.
