I haven't played too much of RR showdown but the few times I've encountered an ursaluna it was always obnoxious. Kept in check by the other bullshit in the tier though.

Mostly it was the expected guts/headlong rush/facade/ice punch/shadow claw shit but I saw a bulletproof assault vest variant with ice punch and power-up punch used as a bullet seed mega sceptile counter, I saw a rock polish variant, a scarf variantand a yawn/belly drum variant that I thought was bulletproof because it had a sitrus berry. After a will-o-wisp, I discovered it was, in fact, guts.

This is what I learned that day:

+6 252+ Atk Guts Ursaring Earthquake vs. 252 HP / 252+ Def Tangrowth: 349-411 (86.3 - 101.7%) -- 12.5% chance to OHKO
