Thank you for the entries, guys! Major props to Phazon00 in particular, for writing the first entry in the Threats section! Unburden Hitmonlee is indeed a major threat to Rain teams, so nice choice :D. I made some slight changes, though - swapped places for Hi Jump Kick and Close Combat, since the former's higher base power is more desirable, imo. Also added Mach Punch and Jolly Nature in Other Options.
I had to re-write the Shortcomings section for Hitmonlee, though. Make sure when writing this section, tailor flaws and checks that would hinder its ability to beat Rain teams, not general flaws and checks. Nonetheless, your Hitmonlee entry has been added >:D
/B/utterfree, I'm rather hesitant in adding Beartic yet. Its SR weakness, neutrality to water, and lower Speed than slow Swift Swimmers like Gorebyss & Omastar are off-putting traits. However, it does have desirable traits, such as its base 110 Atk stat paired with STAB Ice to remove Grass-types, Night Slash to remove Slowking, and Superpower to remove Ferroseed & Clefable. If anybody else have input on Swift Swim Beartic, I would be grateful if you share your experience with us! I would have to test Beartic myself, as well.
speed ghillisniper, I think Magneton deserves an entry in our guide, since being able to trap Ferroseed is a good trait, and it does offer some useful bulk, resistances, and firepower to the team. However, I am not particularly bought on the move choices. For one, I believe Metal Sound may be a better option over Rain Dance. The lack of Damp Rock makes Rain Dance not as useful here. In the other hand, Metal Sound would ensure that Magneton would always beat Cosmic Power Sigilyph.
Under shortcoming's section it's also worth noting that Magneton cannot touch Lanturn, Electivire, and Manectric. I would add HP Ground under Other Options to better deal with these threats in exchange for quickly dispatching Ferroseed.
