You could try throwing in some Burning Towers to pay for the Shards of Readiness and get out Elixirs faster. Other than that, it seems like a pretty good deck.
I tried using Burning Towers, but I ended up with a bunch of Fire quanta while I was trying to get Steam Machines with like 1-2 Sapphire Towers. So I traded out the Burning Towers for Sapphire Towers.
@rotface: Thanks! Grinding using premade rushes get boring, so I decided to try out some upped decks using new cards in Trainer.
