Oh, ok. Wording was misleading.
From which set and which attack and does he have a boost?
Purely Special
Ok, cool, thank you for pointing out weaknesses that has already been said. Now, as a rater, can you think of any way I can handle these threats without gaining very many others as well as changing the team as little as possible?
I am not a good rater. However, Latias looks overloaded -
A dead Latias can mean a 6-0ed team. I once had this problem with BulkyGyara. However, your Pursuit-weak ScarfTias is a even worse "pin" then my wish-supported BulkyGyara. The best way to fix overloadings is to add support. However, I have no idea how to do so without breaking everything up - I don't know your team sufficiently.
