Just one?
Because that won't necessarily be reliable enough to build a deck around.
If its on the bottom, and it's your whole strategy, youre kinda screwed.
I'd just make a generic kind of air deck: Flying Owls Eyes, Wyrms/Dragons, Wings, Shockwaves and then Add fire mark (include deflags to add PC, and to not waste fire) Then just add your blue nymph as a show off-y card
If the opponent has PC, itll only survive to do 40 damage.
But If you are playing agaist elements with no Permanant control (
and
to a certain extent) you can accumulate them, and imagine the fear building up in the opponents eyes.
Also, a completely Unstable Gas based deck will be as useless as having insurance on a cardboard box if you come against any spell reflecting shields.
