I am looking for suggestions to round out the final 2 members of my team for Silver in game (and eventually port to stadium 2)

Heres what I got so far:

Typlosion
Flamethrower
T-punch
Sunny Day?
Rollout?

Raikou
Spark/Thunder
Reflect/Raindance
Crunch
Roar/dig

Slowbro
Psychic
Surf
Ice punch
Shadow Ball/Amnesia

Machamp
Cross chop/submission/vital throw
EQ
Strength?
Something else

Pokes I was considering were flying types such as crobat, skarmory, Dragonite or aerodactyl (although id have to wait), Donphan (shares EQ with machamp), Bellossom (horrid movepool for ingame), Umbreon (doesnt have much coverage), Golem, Miltank/other normal types that can shadow ball ect

Im open to anything including switching guys I have right now (within reason)
Thanks in advance!
