Introduction: Mega Gengar. Back in Gold and Silver, the 2nd pokemon I ever caught was a Gastly in Sprout Tower. That gastly evolved into a Haunter then later a Gengar. Gengar has only gotten better and better and that remains true with its mega evolution. Able to trap almost anything and reliably assassinate key threats in the enemy team, this ghost can quickly become the definition of fear.
If played correctly, this thing is a nightmare. Before Mega evolving, Gengar has a ground immunity, which can be useful. After mega evolving Gengar can outrun almost anything, and can pick off weakened threats, or can kamikaze a threat. Shadowball for STAB and isn't resisted by much in ubers. Sludge Wave kills fairies and can also hit for neutral damage. Taunt can stop foes from setting up on gengar, forcing it to attack. Destiny Bond allows the foe to faint when it delivers the final blow to gengar. This enables Gengar to take out pretty much anything as long as it goes first

Yveltal, the bird of destruction..or is it death? Whatever, its a dark type that does damage, whic gengar appreciates. Dark Aura and black glasses boosts all dark type moves. Sucker punch bypasses speed and hits with 80 power. dark pulse punches holes in teams. Oblivion Wing gets STAB and allows Yveltal to heal while heat wave hits steels. Thinking about replacing it with u-turn to switch to gengar to trap things.

Switching into Ho-oh is never really fun. Burns lower attack and hurt you ever turn. Choice Band has Ho-ho hitting with real strength. And regenerator keeps health high. Brave Bird has recoil but hits as its strongest move. Sacred fire has a 50% burn chance which can shut down some sweepers. earthquake hits steels and has good coverage. Sleep Talk is to catch Darkrai off guard and punish a dark void. Also lets Ho-oh switch moves while sleeping. Could switch out Band for life orb and sleep talk for recover.

Latias can beat groudon-primal, support the team, and give 1 team member a 2nd chance with Healing Wish. Draco is basically a nuke that not many pokemon can take repeated hits. Psyshock hits the physical side and makes Latias harder to wall. Defog clears hazzards and Healing Wish brings ba team mate back into the fight for the cost of Latias itself.

This thing is on every team, and for good reason. 1 weakness, hits hard, hard to kill. Stealth Rocks is the best hazard in the game. Huts switch-ins. Blades is Groudon's strongest STAB move. Lava plume doesn't hit phyically and has a 30% chance to burn. Further boosted by Desolate land. Stone Edge hits flying types hard. A change I can think of is using

The team Anchor. Xerneas is the best Fairy in the game hitting hard without any boosts. Geomancy is terrifying. With power herb its special attack, special defense, and speed double in 1 turn. After that, if a team is un-prepared, it can run through entire teams. Moonblast is boosted by STAB, Fairy Aura, and has good coverage. Thunder hits Ho-oh which can check Xerneas. Focus Blast is for coverage and for Dialgia, which is also a threat.
If Focus Blast doesn't get more use(Mostly Moonblast is enough) may replace with Aromatherapy.
