I have I have one Ground type and I don`t want to switch Grotile, Lucario, Scizor or Steelix. I have: Steelix(Lv 21 no ground type moves) Grotile(Lv 24) Scizor(Lv 7,currently training) Lucario(Lv 24) Luxaray(Lv 32) Haunter(Lv 22)
Your Steelix should do fine, as it walls Raichu's STAB. When Grotle reaches Level 32, it evolves into Torterra, who learns Earthquake, as well as having a Ground typing that walls Raichu STAB.
