I built this team around M-Cross+Zyg core. M-Cross beats Ferro, Tang and Bulu, mons that are able to wall Zyg, while Zyg beats Pex and can pressure Fairy-types with strong CB-boosted attacks. Guts > Moxie on M-Cross to beat status spreaders like M-Sableye. Zyg runs CB set for sheer wallbreaking power, and ESpeed allows Zyg to act as a revenge killer and beat weakened faster threats. Although Zyg can heavily damage Fairy-types, this core still dislikes them. I added Heatran in my team. It walls many Fairy-types bar Fightinium Z variants of Lele and Magearna. Heatran also sets up rocks and improves my team's matchup against stall. My team is very slow, so I need some fast mons. I added Scarf Lando and Ash-Gren. Lando provides Defog and Speed control, as well as a Ground-type immunity and a second Volt Switch immunity. Stone Edge is for Zard-Y and Torn-T. Ash-Gren gives my team more special attacking power and speed, can put Spikes to chip opposing team and can act as a wallbreaker or late-game sweeper. Both Lando and Ash-Gren appreciate their checks like Tang, Bulu, Ferro and Pex(for Ash-Gren) being KOed by M-Cross or Zyg. Opposing Ash-Gren is able to fuck easily beat my team, so I need a switch-in for it. I added Tang in last slot. It checks Ash-Gren and other special attackers like Koko and provides another Ground-type resist. HP Ice is for opposing Lando and Zyg. Sludge Bomb is for Bulu.

This team is designed in Heracross. The main idea was to look for something solid and well covered among all. When I added Koko, it occurred to me to put Tran with Npower taking advantage of the terrain's shifts. Greninja with Spikes to press more to the contrary and with Specs more power. Latias hwish to give support and Landorus is my only Defog with speed control. Punishment seems useful to me instead of hp ice that I already have in Koko.
