Chansey is better. But Blissey still has her niches.
Why would Chansey be better? O.o
Because of Eviolite. However, Chansey's SpAtt is very low, so no Flamethrower, and you lose access to Leftoves... So, while it may be considered better, Blissey still retains some value. --- N2DS FC 4785-5574-6866 Pokemon X IGN: Ema Safari Dark: Pawniard, Crawdaunt, Inkay
