Since rain is apparently staying for now, I don't see why Manaphy won't get banned especially when Latios goes.
MANAPHY DOES NOT DIE. Seriously, it just doesn't. The only way you could win against a bulky Calm Minder really is by using Trick or Critical hitting it or hitting it really hard right away and not letting it get one since after Calm Mind+Reflect/Acid Armor, it's like game over (if it is mono-water Manaphy like that one, Vaporeon, Burungeru, and Suicune can Water Absorb but they can't really do much of anything else to it barring Suicune). Those carrying 2 attacks can also choose to beat those with Energy Ball or carry Icebeam for Dragons and Grass. The only Electric attacks that really threaten Manaphy are Specs Stabbed Thunders. After Calm Mind, even those aren't a problem usually and won't be without stab.
And Landlos should go. Checking Damage calculations with 1.3, you still murder everything and the fact that it hit harder than it should have makes little difference since again, Sandstrength 1-2 hit koes everything anyways and +2 allows it to ohko physical defensive Skarmory and 2 hit ko Brongzong in Sand with Stone Edge which is just messed up. It's silly to assume that there is any large difference between 1.33 and 1.5 on a pokemon already as strong as Landlos.
