Tell me what you think
Typical lead Tyranitar. Stealth Rock is an obvious choice. Taunt shuts the other lead down if they try to setup anything. Stone Edge and Crunch do a good amount of damage otherwise.
Hippowdon is a second user of Sand Stream to ensure that Sandstorm stays in the game in a heavily weather-influenced OU metagame. This hippo is a pretty good wall. Slack Off is great for lasting power. Toxic and Whirlwind are able to poison multiple Pokemon.
Hidden Power Ice
This thing is awesome! It can OHKO many Pokemon thanks to max Attack EV's and Sand Force. Gravity makes nearly every Pokemon vulnerable to Earthquake. Hidden Power Ice takes out Dragon types and opposing Landorus. U-Turn allows for a quick escape if needed.
Hidden Power Fire
Magnezone covers Water types, which most of my team is weak to. Switching into Pokemon that have a hard time damaging Magnezone allows me to setup Substitute. Hidden Power Fire destroys other Steel types.
Skarmory is a nice wall. It can outstall most other Pokemon while setting up Spikes. Whirlwind is useful if the other Pokemon tries to boost its stats.
Hidden Power Fighting
I love this Pokemon! The idea is to switch in to Chandelure whenever my opponent uses a fighting or fire type move. Much of my team is weak to those two types, so Chandelure provides excellent coverage. Choice Scarf allows it to outspeed most Pokemon. With max Special Attack EV's, this Pokemon hits quite hard. Its Fire Blast packs a punch.
