Ludicolo

Ludicolo is a Pokemon that can work well in just about any tier. It has great typing offensively: Water / Grass STAB moves coupled with Ice Beam boast perfect neutral coverage (aside from against the irrelevant Shedinja); and defensively: a 4x resistance against Water-type attacks is a big plus, on top of handy resistances to Ground and Steel. More perks that Ludicolo can lay claims to include decent Special Attack and special bulk, access to abilities that allow it to excel in the rain, and a movepool chock-full of options, both offensive and defensive. However, both Ludicolo's damage output and Speed are underwhelming outside of rain. Additionally, physical variants require a boost from Swords Dance to do any significant damage, and Ludicolo's attempts at sweeping are totally shut down by paralysis and hindered by Sticky Web. Finally, its middling physical bulk means that it can easily be overwhelmed by the abundance of physical attackers in the tier, and to top it off, Ludicolo suffers an unfortunate weakness to U-turn, a rather common attack in UU.
