[B]How to use: [/B]Make progress with arceus-ghost, once the team is softened, hard reads with miraidon can usually clean up. Zacian confusehax and status from dondozo and clodsire can force situations where ghostceus can set up without fear of status, but it can generally perform even if burned or paralysed.
[B]Weaknesses: [/B]PH taunt qd mons that dondozo can't handle (especially ghostceus), generally you can try and power through these with your ghostceus or with zacian but it can end up pretty matchup fishy with what PH sets can beat what teams. Try swapping around clod and dondo's phazing moves if need be.
[B]Effectiveness: [/B]Got to top 5 on ladder pretty easily, won several games against reputed players.
