Gliscor is the first that comes to mind, the Sun weakens his Water weakness and can power up Fire-fang(if you want to use it) and he is immune to sand damage and can use it to stall. Flying Type. Neutral to Rock. Not Uber. Pretty bulky 75, 125, 75 defenses. 95 attack stat that can be boosted by S-Dance. A good movepool that lets him Sweep, Wall, Tank, and even baton pass.

Flygon is good, has things like Fire-punch and Fire-blast that get boosted by sun. He is immune to Sand. Levitate. Resistant to Rock. Not Uber. 80 in all defenses. 100 Attack, 80 S.Attack. An amazing movepool.

Claydol's water weakness goes away with the sun, and he can stall in the Sand. Levitate. Resists Rock. Not Uber. This thing is a Wall/Tank. He has base 70 in both offenses but his S.Attack can be boosted with Calm-mind. A great movepool for Tanking, Walling, and Supporting all that he lacks is a recovery move.
