For Decidueye, I am solidly convinced that Miraidon and Bellibolt are the preferred options for the raid. Miraidon really has no equal as the heavy hitter, and Bellibolt is the best support mon. But the annoying thing about Bellibolt is that Decidueye likes to use Leaf Blade against it, and that’s a high-crit move. Whatever weird AI is going on in this raid, it seems like Leaf Blade crits about 75% of the time. Maybe it’s far less than that, but suffice to say it seems like Bellibolt eats a lot of crits and it sucks!
I posted Torkoal earlier in the thread, and obviously the Shell Armored tortoise doesn’t worry about crits. But, Torkoal isn’t an offensive help at all, because it can’t boost and it doesn’t have SE Stab against the Flying owl. So I decided to tinker one more time with the Decidueye raid, looking for something that plays more like Bellibolt, without as many maddening crits to deal with. Here’s what I’ve been using in team raids in the Decidueye rerun, and it has been pretty fun:
Rotom-Fan @ Leftovers
Tera Type: Electric
Ability: Levitate
EVs: 252 HP / 252 Def
Bold Nature
- Thunderbolt
- Reflect
- Will-O-Wisp
- Nasty Plot
Rotom-Fan is not as good overall as Bellibolt for support. And although I have not tried it solo, I doubt Rotom would be very good in that mode, because it probably can’t stay healthy enough to win solo like Bellibolt can (although soloing with Bellibolt is a slow grind and not much fun IMO). But in a team setting where there are a few Miradons and Bellibolts on the team, Rotom-Fan plays very well and contributes offensively and for support.
Lead off the battle with WoW to burn Decidueye, and then follow it up with a Reflect to make Decideye’s early attacks little more than love taps. Then get a Nasty Plot or two before joining in the offensive brawl. Refresh the Reflect as necessary, because it helps a ton later in the battle when the owl resets its debuffs and Swords Dances before going into double-attack mode.
The key thing for this Rotom is because of its Electric/Flying typing, it resists everything except Spirit Shackle from Decidueye. Whereas with Bellibolt, it is neutral to Leaf Blade, which makes it preferred by the boss, and Leaf Blade is a high-crit move. With Rotom-Fan, it gets hit most often from Decidueye’s weaker and, most importantly, NOT-crit-happy move — Spirit Shackle. This typing advantage is not enough to supplant Bellibolt as the top support mon, but Rotom is a relieving change of pace and is easy to play.
