I made a team with SD Diggersby, but I can hardly find a pokemon on which I can set up. On its analysis, it is written that it can come in on Heatran or Blissey, the first can Lava Plume and burn, and generally Chansey is prefferred to Blissey and can easily Toxic. So, which pokemon can be set up bait for Diggersby ?
Diggersby forces a ton of switches, so it is best to set up on something it forces out, such as Aegislash, Heatran, or Chansey. Obviously, these Pokemon can harm Diggersby if it switches into the wrong move, so be sure that they won't use such a move when you switch it in (for example, you can bring it in when Chansey is going to use Softboiled, Aegislash is going to use Shadow Ball, etc)
Delibird is Amazing, Blissey's only real advantage over Chansey is the fact that Leftovers helps it handle residual damage a bit better. In Gen 5, perma sand (not to mention sand stall, where Blissey had the clear advantage) and volt-turn were very common, so Blissey, which handled these things better, had a reason to be used. Now, sand is no longer permanent, volt-turn teams have become much, much rarer, and sand stall no longer exists. In addition, the most important targets of Blissey's Flamethrower, Scizor and Ferrothorn, have gone from being metagame-defining to being less prominent (but still good) threats. Now that none of Blissey's advantages are very important while Chansey's massive bulk advantage is still as prominent as ever, Chansey is the only one of the two that should ever be used.
