DD Mega Alt destroys the team after +1, which is problematic when Alt can set up on half the team. Alt gets free Mega/Boosts on Lando, Ttar, and Latias. KOs Jirachi after some chip damage w/ a +1 EQ and Manaphy is ohko'd 43% of the time with +1 return after rocks.
Altaria wins if it's in at the same time as Latias. ABR has a few options; go to Lando, go to Jirachi or sack Latias/another team mate. Lando isn't that good of a switch on the +1 since Alt can spam roost and stall Lando out of EQs if its mega evolved. If not, all lando can do is knock off in which case Mega alt gets a few free DDs before it's forced to roost and evolve. If Jirachi is the switch in, it's in danger of getting chunked by a Return, in which case it'll get KOd in the future by a +1 EQ from alt.
Scarf keld is the preferred partner, since it has really good synergy with Mega Alt against this team. Keld puts pressure on both Lando and Mega Lop, forcing the switch. It's best answer, Latias has to fear the double into Mega alt. ABR can try to switch into Jirachi to predict mega alt, but even then it's not that great since Keld is fine just staying and spamming scald to give MAlt the chip damage it wants to ensure the KO with +1.
Even if Alt doesn't successfully sweep, it'll still probably chunk/kill Keld's answers in Lati, Rachi, or Manaphy, which means worst case scenario of the failed Mega Alt sweep is setting up Keld for the late game sweep w/ Secret sword or scald.
