Smashville, Pokémon Stadium 2, Yoshi's Island Brawl, Final Destination, Battlefield is 5 good starters. If you really want two more, Lylat Cruise and Yoshi's Island Melee maybe?
If so, striking should be 1-1-1-2-1, where P1 strikes 1, P2 strikes 1, P1 strikes 1, P2 strikes 2, and P1 strikes 1 last stage.
Counterpicks: If 5 starters, any stages above that aren't starters should be CPs. Also, Fountain of Dreams, Green Hill Zone, Lavendar Town, Pokémon Stadium, Skyworld is my recommendation. 3 bans is probably good. [Temple, Halberd, Rumble Falls, and Warioware are also all options.]
