I feel this deck doesn't have a strong enough early game to survive against more aggressive decks. The expansion brought ridiculously powerful early game for some classes so you have to be able to compete with the likes of Skybarge. Let's investigate the deck's early game minions:
Turn 1: Eternium Rover. A very powerful 1-drop, the only ones in the deck. You can't mulligan for 1-drops consistently. You'll often end up skipping turn 1.
Turn 2: Dragon Breeder/Ritual Chopper. You're either playing a River Crocolisk or a slightly better Heroic Strike. Ritual Chopper is bad if you go second and your opponent has no minions/your rover kills their 1-drop. I think Dragon Breeder is too greedy in a midrange deck.
Turn 3: Scion of Ruin/Smolderthorn Lancer.
A worse Rabid Worgen isn't very good to play on 3.
The Lancer is too often just a 3/2 when there are no proper targets available on 3, but it can be quite strong early on.
Turn 4: Frizz/Poacher/Voone.
Frizz is good to play on 4, but in the short term she's effectively a yeti. In a deck with 10 dragons it takes on average 3 turns to draw a dragon, making her dangerously slow for a more aggressive deck.
Poacher: extremely powerful if your opponent has a dragon, but you can't solely rely on that. You need other good 4-drops too. This card will quite likely be very strong in the early days of the expansion.
Voone is a 4/3 for 4; horrible tempo. When you play him and duplicate your dragons, that Pirate Warrior plays a 4/2 and re-equips their 3-cost weapon.

You would copy the opponent's Elysiana :)
