Arcade was pretty easy to get silver print(well, actually, all were easy to get silver, except factory, which is pretty hard sometimes).
For aracade I'd say if there's nothing that benefits you, aim for a null or board effect.
And for Hall you used Electivire w/
Earthquake
Ice Punch
Thunder Punch
Cross Chop?
I guess Shedinja is a problem... Use a Breloom to win
Mach Punch
Seed Bomb
Facade
Spore/Swords Dance
Item should be Toxic Orb, and ability should be Poison heal. If you last longer than one turn you begin to heal, and if you start with Spore you should be set to go. Facade doubles in power after Toxic Orb, and Mach Punch gets rid of Breloom's sub-par speed. Seed Bomb is there for STAB and for hitting water, ground and slow rock types. Only problem with this set is ghosts, who will eat you for lunch. As long as you stay away from them you're good.
