>>17280746>Lay rocks down.>Heatran, Volcarona, Charizard, Infernape.>Ferrothorn>Rocky Helmet. If you're aware that Genesect is a huge U-turner, use things that will regret making it use U-Turn. Rocky Helmet Heatran is a great stop to Genesect alongside rock damage.
Genesect gets stopped way too many times by Heatran alone, because of Flash Fire., forcing it to use U-turn, as Ice Beam and T-bolt or whatever other move they have will be useless against Heatran anyways. Rock Damage and rocky Helmet adds over time, you know.
Genesect has shit defenses.
