Here's my take on a Steam Machine deck. It's super fun!

Steam Machines are unupped in order to take advantage of the lower cost.
I was quite surprised to see that the cooldown effect is part of the active skill and isn't a passive skill like swarm or mummy. That means that lobotomize removes it, leaving you with a Steam Machine with high attack power that doesn't decrease.
I tried it out and it's pretty fast. I tinkered around with it a bit and switched out two Steam Machines for Arctic Squid, removed some Sapphire Towers in place of Aether Towers, and changed the mark to
. Parallel Universe + Shard of Readiness + Arctic Squids is a good stalling method while growing the Steam Machines.
It sure makes a mockery of other speed decks without control, too.
