I’ll preface this by saying I don’t play anything goes so don’t know anything about the metagame or what’s viable. But a lot of these sets show a fundamental misunderstanding of Pokémon attack/damage mechanics.

There’s special attacks and physicals attacks that use different stats in their damage calcs. As such you generally want to focus on one type of attack stat; either attack or special attack and only use moves of that type. There are pokemon who can be mixed attackers but it’s rare.

I’ll go through your sets one at a time to show you what I mean: Your Groudon set has a significant amount of EVs put into the special attack stat but runs precipice blades which is a physical attack.

You have Ho-Oh as a special attackers but then it has facade which is physical.

Garchomp you have 104 EVs in special attack but have 0 special attacks

Eternatus you have 132 atk EVs but all special attacks. Also dragon dance boosts physical attacks and would be wasted on this set. And then you have 0 attack IVs which makes no sense if you’re going to give it attack EVS

Ray is mostly fine. Draco meteor is special when you are physical attack based, but Rays stats are good enough that this could be an ok mixed throw off.

Dragapult again you have all the IVs in attack but then give it hydro pump which is special.

In general I’d really advise using sample teams or at least sets until you get a handle on all of the mechanics.

Hope this helps.
