As much as I do tire of seeing starters and eeveelutions (and pseudo legends) dominate everything ever, I do much prefer Vaporeon to Gyara and Ferali. Sorry :P
I can agree with this. I wouldn't vote for a starter or an Eeveelution in everything (in fact, now that I think about it, probably the only instance for me of voting for Eevee or an Eeveelution would be Eevee for normal and Umbreon for dark), but between these three my vote is for Vaporeon. I've never been a Gyarados fan, and although I like Feraligatr, I would give a slight edge to Vaporeon here.
Evacuate? In our moment of triumph? I think you overestimate their chances.
