honestly since i havent played the newer games, is Gogoat any good? i got skiddo from the egg and im unsure if using him is worth it. his move kit doesnt look amazing but his stats are 531 and thats pgood
This actually is fairly easy to explain with Episode 18 information.
Lin's Hydreigon can be assumed to have gone through the process of giving it 252 EVs in every stat. A Hydreigon with 252 Sp. Def. Evs and 252 HP EVs will survive a Moonblast from a 252 Sp. A. Ninetales with a speedboosting nature 6% of the time. And Alolan Ninetales best set, the Aurora Veil one doesn't have 252 Sp. Attack EVs. It has 8. Under those conditions Hydreigon will never be OHKO'd by Moonblast.
Then if Aurora Veil isn't up, which in this case I think is a safe assumption since there is no hail that we can see during the battle, Hydreigon will always OHKO Ninetales with its follow-up Flash Cannon.
Which way did you change the time? Doing that can lock your weather more or less indefinitely if its in the wrong direction. Forward specifically. Never ever ever change the time forward while playing the game.
Honestly if the weather is that bad you should just download the mod to letting you change it. I don't think you have to have the rest of the pack and you should be fine just deleting the rest. If you are uncomfortable doing that you can also upload your save file and I'll change the weather for you. I think the weather can be reset using tools.
