Nightmare is in my used pile, Dark Tunnel is your's, so if you changed it to that, you would get the Ventus boost which is 140, putting Alpha Percival at 860, and putting Elfin at 870, so I still win.
Oh darn I forgot, BUT according to the tourney topic I don't have to use my official team for this round, SO I'm going to change my last move.Instead of Ventus, I change to Aquos and play Power Triangle, giving me +200gMe: 1050gYou: 950g
