Sassy Nature(-Spe, +SpA) This nature is pretty bad for M. D. Venu. Thus, a modified set
- Calm Mind
- Leech Seed
- Draining Kiss/Moonblast (Most of his team dislikes Fairies)
- Thunderbolt/Moonlight (For D. Haxorus)
Mew is a wild card, it depends on Nature.
The strategy is to lead with Giratina, Thunder Wave, then Dragon Tail, Pain Split if HP gets low until all pokemon are paralyzed or Giratina dies. This only works in Hard Mode, which disables both the user and AI from healing, otherwise he would spam Full Restores, disrupting the strategy. You could try, but he has 2 Full Restores and 5 Full Heals I believe. Might be wrong on that. I mean, you would just have to spam T-Wave until he runs out of Full Restores, but he might attack and KO you. After Giratina goes down, you can try to set up with D. Venu and sweep/break with Moonblast/Tbolt, though you can play more stally and try to wait out Leech Seed and Draining Kiss. Empoleon is your primary anti-Flygon, try to land an Ice Beam. Excadrill can hit everything hard, but make sure everything is slower than it or paralyzed before it sets SD to sweep. EQ Moldbreaker is the only way to hit D. Volc supereffectively, if you don’t have it, use Iron Head. Gengar is to spam SpexHex, boosted by the Para on everyone. It can Dazzling Gleam or T-Bolt to hit everything neutrally, but Hex is more powerful on neutral hits. Weavile is a revenge killer, you could Choice Band it, and just swap it in when a weakened mon needs to be finished, then swap out.
