egg's not better than lax
Salamence sounds like a better fit than Dragonite in my opinion, it only existed through the last two gens but it was incredibly overpowered in DPP and had more tools to work with on ADV. Nite was barely useful on RBY and GSC so that doesn't exactly speak a lot about dominance.
Then we run into the same issue as with GSC Celebi. It seems that the consensus here is that Celebi's existence in OU should be disregarded for the most part. Following the same logic, I don't think Salamence deserves anything here for only one gen.
