The current list I'm running has -2xArcane Amplifier, -1xDaring Fire-Eater, -1xPyromaniac and -1xJan'alai, the Dragonhawk in favor of going 2-ofs on the dragon support cards, 2xMessenger Ravens and a pair of Water Elementals, and so far it's been extremely successful, but I really want to try out the Hero Power package as well, as I think it's got some actual potential now, so when the rest of the adventure cards get released this is the version I'll be testing.

Full disclosure however, I'm pretty sure my current list will end up being better than this one, as the Hero Power package will probably end up being a little too slow for a tempo deck, but we shall see. It will mostly depend on how good the Arcane Amplifier ends up being.

The concept is really simple, everyone is running super greedy decks that effectively skip their first 1-3 turns, generating little to no tempo, and this deck consistently plays well statted minions while generating value and eventually overwhelms the opponent. 

So far it's blown everything out of the water besides Rogue, which feels very slightly favored for us, but only just barely, and Rez Priest is a bad matchup, since without spells we're at the mercy of RNG for a generated Polymorph, and their stupid 2/6 taunts shaft us pretty hard since we don't go wide.

Another idea that I had was to cut the dragon package entirely, go all in on the elementals, replacing the Whelps with that 5/5 Draw-a-card elemental and the Legendary dragons with some Frost Elementals, only keeping the Twilight Drake and replacing Dragon Breeder with Sunfury Protector. That version would probably be a bit better against aggro. Overall I don't know if it would be better or worse, but it would definitely be more budget. Personally I like the card generation that Dragons offer, it keeps you with a decent hand size for your Mountain Giants and lets you keep applying pressure without losing tempo.
