HP Grass for Swampert? Yes.
U-Turn for Celebi? In the above calculations, Fire Blast does the same damage as U-Turn.
I overlooked this when examining the calculations. Thank you.
If that's the case, why not find a way to work Roost in there?
Yes, "why?".
I would personally advise not using roost on such a flygon. If you plan, as you said, for this to tackle stall teams, then I would personally advise against it. Because stall teams lack offensive power which they will compensate with residual damage, the notion behind flygon with roost becomes absurd. When you become stacked up with toxic, stealth rock, Life Orb, along with other damage from your opponents pokemon (you 2HKO celebi, but what about it's OHKO HP ice?) and other forms of damage like leech seed. Roost is certainly an option, but you could be taking as much damage as 30% each turn, so roosting every second round will give them the opportunity. Besides, you sacrifice one move which could be important in destroying a few enemy pokemon.
