You could have added some pots for the dragons 
Bah, That would undermine everything important about this deck. Don't use the fire because that's what you WANT them to think you'll use.
And I think the quanta ratios are actually proper for the dragon counts. There's only a 1/7 chance of getting a pendulum, and since they aren't upped that'd mean too many turns to actually use the pot. I think it's better to just go all in on air to get the dragons out faster.
