Before i start, worship sceptiles. anyways,
Absol is good but dump baton pass so its moves will be
Double team, Swords dance, return and shadow ball
Swampert rules, i wouldn't use roar though although it sometimes comes in handy. Thats just me though i would replace it with one of your one or the other choices, preferably toxic.
Can't complain with Alakazam for sweeping. Nice.
Great here as well. Not bad.
i have never used any hp (insert name here) attacks so i don't know what they do. I hate focus punch. Ive never used a brellom anyway so i don't know how good they are.
Out of the three altaria. it isnt too bad and you have given it a good moveset.
A good team just a few minor adjustments needed.
