While I do like the idea, fights are likely to last extremely long and you don't have anything to counter steals/deflagrations. If you don't mind that, shrink the deck down a bitdidn't know the chance is that high and it should be fine as long as the enemy has some strong creatures. If not, mutation might help, but unupped that's a risky game.
A while ago, I had a similar (rainbow)deck based on upgraded dissipation shields, quantum towers, antimatter and protect artifact. For damage I chose dune scorpions, because one single strike would be sufficient if I could just survive for long enough. It was quite fun to play with and not too bad either. Might also work well with some fallen druids...
