This tier looks so fucking cool. I don't have a lot of time now, so I'll probably get more into it later, but for now I can say that Cradily-Gyarados looks like a really strong defensive core, only weak to Fire and Grass (off the top of my head, please add any that I may have missed). Pair that with Metagross, and you're starting to look pretty dangerous. Steel is a pretty good offensive type here, Metagross can afford to run MM + BP as its only moves because it's only resisted by Ice + Rock, leaving two other slots open for Agility, SR, Gravity, or using Ice Punch for coverage against Ice, or Return for Rock.
