[Super Mario Bro]

I would like to nominate Abomasnow for A-Rank. As someone who has played with hail extensively and successfully, I can confidently say that Abomasnow isn't usually even the Achilles Heel of the team. It has nifty resistances to Ground, Water, Grass and Electric and decent bulk, which give it plenty of opportunities to set up a Substitute and proceed to wear down the opposing team with Leech Seed + residual damage. It is also fairly unpredictable, as it has quite a few effective sets, like Choice Scarf, Choice Band, and even an Expert Belt wall-breaker set.
