[OPTIONAL CHANGES]

Dragonite can run some interesting moves, such as Heal Bell and Haze, but those should be only used in a bulky support set, the problem lies in that Heal Bell is incompatible with Multi Scale;
Substitute can be ran in the DD set in place of an attack, making status less problematic, but loosing coverage;
