Vaporeon. It has the best move of the eeveelutions. My source is beating the game and getting almost all the legendairies with vaporeon or garadose. Now as in recognizable points out, Glaceon is better for drag or. But Glaceon is a week ice type and for ice I recommend mitushide with lapras or articuno. Not Glaceon. Glaceon goes down too fast. That's why I say vaporeon. Articuno has high speed and I conquest that makes blizzard hit. So go with vaporeon because grass types in conquest are rarely used. Truthfully I use gyardos as my Pokemon. Then warlords with Mewtwo, groudon, articuno, dialaga, ochi with aggron and either nobungas with zekrom or hideoshi with reshiram.
