So the bands that you requested I put on there, with defog on ho oh so that we are not too pressured by rocks. The Gar set is interesting, but in my opinion provides the most utility towards this team. This m-gar set can dispose of almost all support arcs, and also things like mono attack zygarde and choice scarf yveltal if you're behind a sub on switch. The ability to dispose of support arcs is great news for band ygod and band ho oh. For a secondary fogger to ho oh, i chose giratina. Giratina offers a lot of utility as a wall, status spreader, and reliable defogger. Also can serve as a groudon check. Roar can be opted over toxic, if you prefer. Groudon is there for rocks, and hp ice is an interesting choice as it doesn't give salamence free turns, and also can catch zygarde by surprise. Roar was selected as a xern countermeasure, but overheat can be opted for as well. The last pick of this was arc poison. Arc poison offers the unique niche of a xern and marshadow check, and can also serve as a wincon if played well.
