My team is almost complete, except for one thing, my Haunter. I just need to evolve him, then my team is complete. But should I use him? Here my team:
Sandslash lvl 35: Cut, Poison Sting, Slash, and Dig.
Dodrio lvl 35: Drill Peck, Tri Attack, Fly, and Fury Attack.
Haunter lvl 26: Lick, Confuse Ray, Night Shade, and Toxic.
Gyarados lvl 32: Thunderbolt, Double Edge, Ice Beam, and Dragon Rage.
Nidoking lvl 35: Thrash, Rock Slide, Horn Drill, and Seismic Toss.
and Venusaur lvl 39: Mega Drain, Body Slam, Razor Leaf, and Vine Whip.
So, should I use Gengar? Please tell me. Thank you, in advance.
