Wassup Blunder,
Can't wait till to see you guys at the next next regional, still relatively new to Smogon and the Agency but your vids with Aim, CTC, sama , suave and others got me into competitive. So I'm still climbing the ladder and it's annoying but it's fun too. I've been really liking Ursaluna as of late and trick room is cool and all but I've been experimenting with two sets: Specially Bulky Ursa and Grassy Terrain. The former is reminiscent of the set that got him banned from UU and inspired by Pinkacross as well. I added some grassy support with Rilla and with Ursa bulk it's kinda like Bax with it not caring about status/ice body recovery. With Grassy terrain and the leftovers your gaining a lot of health back. Being able the stomach hits from Raging bolt, Waking Wake, Ghold and more with your special bulk. And Supporting you you have double ghost spin blockers w/ Pualt and Ghold (who also appreciates the grassy terrain) And with a G-Weeze for hazard control plus spreading burn
and a Assault Vest Zama Because with no SpD investment it reaches a respectable 400 SpD so eating hits from Val and Glowing if worst comes to worst. I've been laddering and I'm not skilled enough to see any major checks yet but you can give me feedback with that as well.

Okay, Now for the More Aggro Version:
This Team features the same Rilla and Ursa core but More offensive in nature, with Rilla being classic banded and Ursa with flame orb. The cool synergy is that grassy terrain cancels out flame orb burn and with one trailblaze your outrunning and threatening to O.K a lot of threats you would be in Trick room but now normally such as Ghold, Tusk(Non defensive), H-Sammurot, Kyurem, lando and literally anything below 327 speed. I opted for terra grass for that little extra breaking power when wanting another Trailblaze for Mola but tera normal is also standard for pure muscle. And something to also remember is your still an Ursa with excellent bulk. G-Weezing sees a return because he appreciates the ground dampening effect of grassy terrain and the extra passive recovery. More standard we have a Hawlucha as a wincon again plenty of encore-able threats, pretty stander Hawlucha things. AV Prima appreciates the Tspike absorption from G-Weeze but also the passive recovery with terrain and as with Zama a naturally high SpD meaning we don't need to invest to reach 400 meaning we have More breaking power with our moon blast and liquid voice Psychic noises. And our last slot is a Expert belt Darkrai used to pick things off and speed control, you could opt for boots but in my testing Rai has been falling short of K.Os so I opted for the belt bc the Ice Dark and Poison coverage is superb.
