>>53100774Teras got Manaphy built in, as in they don't take damage while on the bench.
I don't think arcanine will be terrible, considering he and Gyarados are the big 2 of the expansion, but i wonder if he is gonna have any shot against meta decks like Lugia/Mew.
Assuming you go second with Growlithe and evolve on the turn afterwards you could be hitting for 250 on turn 2.
Gyarados seems a lot better since he can do up to 360 damage altough he needs a ton of energy and you could just instantly lose with an unlucky Magikarp opener.
