Id like him to get an abra, but hes already got beldum for the pshychuc part of his team. He needs to get a gastly so he can get a genger that fills in the ghost/poison part. then he needs a ground type, which if im being honest theres only three Ground types that are actually good. rhydon (ground/rock), onix (ground/rock) and/or phanpy (ground). His team is currently Charmander - charizard (Fire/Flying) Magnamite - magnazone (steel/electric) (evolves to magnazone through thunder stone) Beldum - Metagross (steel/psychic) Lapras (ice/water) Add in gangar (ghost/poison) and then youve got one spot left for the ground type to get a fully balanced team
How about giving him a nidoran f as tank for his Team atm He has charmander/charizard as heavy hitter/dd magnemite/magnezone as shooter/range dd, lapras for water battles ( allrounder =tank dd Support) beldum/metagross as support+heavy hitter if need arises so with a nidoran/nidoqueen He will get a strong tank and later a pure support/healer would round up the whole team
