>>58473241 together in a few minutes, but now that I've had more time to think about it, I think there's better ways to unoptimize Mega Flygon.
>Bug/Dragon means that it loses its Volt Switch immunity and Stealth Rock resistanceI considered keeping it as Ground/Dragon so it still has a 4x weakness, but I think losing 1/4 of its HP to Stealth Rock is worse than just one 4x weakness that's easier to avoid
>losing Levitate means that it loses its immunity to all other hazards>70 speed is too fast for Trick Room but too slow for anything else>I unfortunately had to give it at least one good stat because 620 is too high of a BST for everything to be bad, but I made it special defense because that's probably the least good stat to have be really high>kept physical defense pitifully low>Hustle means that its physical attacks all have an increased chance of missing (say hello to 72% accuracy Scale Shot and 64% accuracy Stone Edge)I didn't want to give it an actively detrimental ability, because that felt like it would be cheating
>even with Hustle, it's still only barely stronger than a base Flygon with Choice Band, which does not make up for the miss chance>special attack increased, but it's still weaker than base Flygon with Choice SpecsIt's actually harder than I thought to make a bad Mega Flygon, since Flygon's movepool is pretty good.
