[DISCUSSION] What Pokemanz should I use?

[DerpyWalrus]

I use Chansey as a wall.. (So original)
her ability is Natural Cure
Bold nature
and her move set consists of 

Thunder Wave
Seismic Toss 
Heal Bell
Soft Boiled

You could get rid of one of the moves since I only have one attacking move and the attacking move doesn't do that much damage because Chansey is a terrible physical attacker.
