I had a cool deck Idea the other day. A powerful combo involving Chansey, Metal Energy, and Unknown N. The Metal will reduce damage to Chansey by 20. Uknown N Reduces the damage by another 30. That means that Chansey only deals 30 to himself. Throw in some Blissey to heal Chansey when he takes to much. Also some Gold Berries and Focus Bands will help chansey cut through the opposition. Some nice backup cards for this deck would be Team Rocket's Meowth and Blaine's Tauros. They both deal damage to themselves and to their opponents, so Metal Energy, Uknown N and Focus Bands really help.
