Hello. This is my first post, so I hope this hasn't been brought up before. Picture this: Chansey is your active pokemon with one metal, one DC, and one recycle (or whatever you use), and a gold berry. You use Double-Edge and pop out 70 damage and 60 to yourself (metal, isn't it great!!). If you are fighting against Pokemon who can only deal out 50 or less damage, save your gold berry for now. Next turn use Blissey and with a lucky flip of heads you now have 0 damage on Chansey, and even if you flip tails Chansey will only have 20 damage. Now for the strategy: Use Hyper Devolution Spray to put Blissey back into your hand, and then double edge again for 70 damage. Use the gold berry between turns and now Chansey (if you flipped tails with Blissey earlier) now has only 40 damage (20 if you got heads when you played Blissey), and has dealt out 140 damage in two turns without discarding energy. Next turn Blissey and gold berry again. See where I am going with this? Item Finders are very helpful with this combo. This strategy has helped me win several games at the local Pokemon Gym, but may not work in all environments (I use Scyther to combat fighting types due to Chansey's weakness). I know there are ways around beating this, but that is true for all strategies. One thing for sure is the little Igglybuff can't harm Blissey's Pokemon Power because Blissey is usually in your hand when it's your opponent's turn. Anyway, hope this helps somebody out there.
