What's this deck for? AI3? PVP?
Also, how do you feel this deck is? Is it suiting your needs, or is something going wrong with it?
Fire mark might work better; you need it to power your steam machines, your UGs, and your fire cards.
Take the toadfishes out. They're both likely to get destroyed and, frankly, their ability won't be used at all, without any death quanta. Take some more steam machines instead, or some arctic dragons.
You also might want some more air pendulums. It'll be hard to come up with a good balance between the air pendulums and the nymph tears. That'll be your challenge with this deck.
The biggest deal is really where you want to go with this deck.
Do you want to try for more of a steam machine-oriented deck, or a UG-oriented deck?
