Get ready for the new me!
The RU Ladder has historically had a massive fetish for terrible Ground-type spinners. It's always been that way since 5th Gen. Claydol was #1 in usage back in BW1 RU, the mighty Sandslash was in the top 20 in BW2 RU (and late BW1) despite being absolutely terrible, and Claydol itself was RU for a long time in 6th Gen despite being garbage as well. Granted, Claydol wasn't that bad in BW1 RU (it was okay and had some decent niches), but it definitely didn't deserve to be in the same level of usage as BW1's top tier threats like Honchkrow and Cofagrigus, and was mostly used by noobs thinking it was the best Pokemon in the world. Donphan is merely the follower of the chain of RU's inexplicable fetish for terrible Ground-type spinners because of the mindset, "They have SR AND Rapid Spin in one moveslot, which means they must be good!", after its fellow contemporaries Sandslash and Claydol. Which is also especially notable because RU has always had other hazard removers who were outright better than the likes of Sandslash and Donphan, such as Kabutops and Cryogonal in 5th Gen.| 21 | Donphan | 9.050% |
ru never ceases to impress. and only heliolisk drops out of their d-rank mons.
| 45 | Dhelmise | 4.957% |
| 52 | Jolteon | 4.614% |
| 56 | Blastoise | 4.215% |
They have also historically maintained terrible/useless mons like Whimsicott in BW RU and Ambipom and Typhlosion in ORAS RU. The RU ladder is and always has been trash from the very beginning.
