Basically, my counter for predicted fire attacks, as with Metagross, Scizor and Ferrthorn, I'm expecting a lot of fire blasts thrown my way. Protect is obvious, Earth Power is mainly for opposing Heatrans, and Heat Wave is just a nice STAB/Spread move Chople Berry is because of Cresselia's Skill Swap, alleviating Heatran's 4x weakness. The EV's are mainly to give it maximum punch without letting go of a lot of speed.

My favorite on the team. Metagross has just always had a special place in my heart since it came out in 3rd Gen. As a result, I felt the need to have it on my competitive team, that and it eats a lot of things I've encountered in random match up for breakfast. Earthquake is my general spread move, and has nice cohesion with the amount of protect and ground immunity on my team, Meteor Mash is my hard-hitting STAB attack, Ice Punch is for those pesky dragons, and I picked Bullet Punch>Protect, purely for the quick finishing blow. Occa Berry is a safety measure in case I really need to get the Ice Punch off, or I'm in a pinch with no Heatran. The EVs are for maximum punch and bulk, because let's face it, outside of priority, there isn't much that Metagross is going to out speed.

My super stall pokemon for the team that i kept slightly offensive since it's a great check to rain teams in tandem with Gastrodon. I run absolute minimum speed on this bad boy to abuse opposing Trick Rooms and slap them in the face with Power Whip or Gyro Ball (depending on resistances and their speed). I'm going to go ahead and say leftovers does not need introduction for this set, as it aims to stall and recover. The EVs give me maximum bulk and even out my defenses in case sand isn't up. it does make sure i favor Sp. Defense by a little bit, for said rain.

My version of support Cresselia. Mainly just my wall and team support. Psyshock is my most offensive attack when need be, pulling a little surprise on any foes with higher Sp. Defense. Icy Wind is for team support, setting up sweep opportunities for Metagross, Heatran, and Scizor. Skill Swap is used to help out Heatran and Metagross (if need be) with their ground weaknesses. The nature and EVs maximize my bulk and even out my defenses to lessen prediction while favoring Sp. Defense by 1 point so as to prevent any beneficial Download. As you may be wonder why i have 6 Sp. Attack EVs, it is to make up for the HP Electric that was given to Cresselia before i obtained her.

The second part of my rain counter, and also the status inducer to be used alongside Ferrothorn. Scald is my best STAB move for the burn, and still gets pretty dangerous with Storm Drain boosts. Earth Power is used as my secondary STAB. Toxic is used for stalling purposes if i am having difficulty eliminating a threat. i used Recover>Protect purely as a means of recovery (obviously lol). The EVs and Nature grant me maximum bulk and a strong defensive presence, especially useful for stalling. The EV spread also allows Gastrodon to survive a Close Combat from Choice Band Terrakion and a Choice Band Outrage from Garchomp at full HP.

Scizor is the last pokemon on my team and is sort of filler, but at the same time is important. It is important because it allows me to counter Tyranitar and opposing Cresselia with ease. Bug Bite is the obvious STAB choice, reaching a silly strong 135 base power, and bullet punch is my revenge killing tactic, doing about 50-55% on many Tyranitar. Superpower is my final attacking option for those Tyranitars and steels that may give me trouble, that i just want gone. The EVs are similar to Metagross in that they give me max bulk and max punch, and the speed is just to tie anything investing just enough to out speed 0-speed Scizor.
