So, let me see now.
Abomasnow being BL is understandable, like. Having that many weaknesses just doesn't do the iceman justice what with the permanence of sand.
Donphan surprises me a little, but I guess that he's outclassed by Forretress as a wall and spinner.
Ninjask being made BL is the first big mistake. Hypothetical situation: Ninjask simply dances before passing the boosts to something like Blaziken, who then uses that speed to 6-0 the opposition with the massive movepool.
Porygon-Z is another shock that just won't be. True, he's slower than Alakazam, but hell, he gets NP, and he only needs one boost in Speed to utterly dominate the BL tier. Yes, Azelf outclasses, but PZ can simply use TR to scare away something then utterly destroy the faster switch-in with his crappy speed.
Now we just need to promote That Fucking Dragon to Ubers.
