Good deck, got me to plat 4. If I had the shards/cards I would take out Soul Stealer and Whirly or Fire Imp to put in a Blastmancer and Morgrul. If someone can test that out and see if it works, please notify me because I think it would be very good but as I said, I cannot test those for myself. Alternatively, if you are missing Scott, Flightless Dragons serve as a suitable tank destroyer and DPS to the enemy master. Drones can be replaced by another 4 or 5 mana minion that can hit flying guys, preferably one that is flying.
Core Cards in this deck:
-Dragon Ball: After the change to the card for the requirement to go from a 3 mana minion to a 4 mana one, it's power is still utilized within Puff decks.
-Spear Throwers: I'd reccomend at the very least 2, as they have well rounded stats, can be divided to take both bridges, and utilize both Puff buffs very well.
-Fire Imp, Defenso Chopper, Whirly Scrat: Good minions that can handle groups well. If you are going to drop one of them I'd recommend dropping Fire Imp and putting in Flightless Dragons or a solid minion such as Morgrul.
