well my altaria set , its supposed to be bulky in both sides and not meant to sweep! When giving it an adamant , it actually decreases altarias needs of taking hits so its not good! With a careful nature and cotton gaurd , its pretty good since he can take hits on both sides, (well besides steel types , ice types , and dragon types) and he can heal off with roost! Altaria isnt meant to go for a sweep but hes good on walling other pokemon
The second set is good ! (since its a different set) . The problems im seeing on that set is that it has less coverage. Mind switching a move for Earthquake because steel types are a pain in the ass. It needs some speed EVs , because , even if it goes for a DD , other scarfers will kill you off
