But I won't have Pikachu during the E4/Champion. Flareon isn't fit to fight against Lorelei, Bruno and Lance, while Jolteon is very effective against Lorelei, has Pin Missile for Agatha's Poison-types (if Kadabra fails) and is neutral or super-effective against Lance. Flareon is also pretty much useless against Blaine and Giovanni (though I probably don't have to worry about those two with the Water/Grass-overkill). Grass-types I can handle with Kadabra's Psychic, since most of them are dual Poison-type, the only exception being Exeggutor and Parasect (which are 4x weak to Bug, aka Pin Missile even though it's a weak move, x4 is pretty much a selling point).
Still, my heart is saying Flareon, while the game effectively is telling me Jolteon. This team is just crazy offbalanced, but there's not much I can do about it. Not to mention that Vileplume and Tangela don't differ much outside of Vileplume being 4x weak to Bug and Tangela only being 2x and not having the Psychic weakness. And Kingler's got a killer Attack-stat but no STAB or anything to use outside of Strengt and Hyperbeam.. -.-
