What really baffles me is that Donphan is so high in OU. He is a cool spinner for sun teams, but i don't think he is that good.
I'm going have to disagree with you here burning man, Donphan is the spinner the Forretress (even Tentacruel) wishes it was. Donphan can smack stuff around with a pretty powerful EQ and if it is ever in the situation to outspeed something (Gengar) Ice Shard can do a decent chunk. With Wish or Heal Bell+Rest support, Donphan can tank hits all day. While not sporting the resistances of Forretress, Donphan doesn't become set up bait like forry does all the time. My favorite spread thus far has been 252 HP / 96 Atk / 176 De. That little bit of power goes a long way of how Donphans plays as a Rapid Spinner, one that finds the middle ground :naughty: between Forretress' and Tentacruel's defense and Starmie's offense.
Let's not forget that it has gotten Hax Veil from DW, which imo can be equally as good as Sturdy.
