Hippowdon

Hippowdown spent a lot of time as a devalued Ground Type, thanks primarily to its lack of a Ground Type Fast Move despite also sporting the full set of original Elemental Fangs and Bite instead. Well, now it's got a strong and very thematically relevant moveset in Sand Attack and Scorching Sands. Now this ruler of the land-hippo stands tall as... an okay Ground Type attacker.  

Best PvE Offensive Moveset

• Sand Attack is Hippowdon's STAB Fast Move, and its overall best option.
• Fire Fang, Ice Fang, Thunder Fang, and Bite all fall behind.
• Scorching Sands is Hippowdon's preferred charged move on offense.
• Earth Power and Earthquake fall short.
• Stone Edge and Body Slam serve no offensive role.
• Weather Ball Rock is good, but lacks STAB. 

Best PvE Defensive Moveset

• Ice Fang and Fire Fang are preferable for hurting Grass attackers, while Thunder Fang is good vs Water attackers. 
• Bite falls behind on defense, even when other fast moves would be resisted.
• Sand Attack is too weak to be good for Defense.
• Body Slam hits quickly and often, but its power leaves something to be desired.
• Weather Ball Rock is also a good option, especially given the raw power of many Flying Type attackers.
• Earth Power is the much stronger charged move, but it's quite easy to dodge.
• Scorching Sands isn't as strong as Earth Power, but it's more difficult to dodge.
• Stone Edge is hard to dodge, though its 1-bar status makes it pretty unwieldy. It's probably best to just stick with Weather Ball Rock if you want Rock coverage.
• Earthquake takes time to charge and can be seen coming from a mile away.
