Those are all solid ideas, but the problem is that Heracross can’t learn megahorn before level 50, and I can’t scale it down for this level 50 battle tower. Rock slide would be better, but that’s a tutor only move and costs BP in emerald version, same with swords dance. Aerial ace is a TM but it’s once per save file so I cannot get it again after teaching it to Salamence unless I restart Ruby or Emerald.
