personally I haven't found much issues with both urshifu forms from non stop testing for the last 2 days. especially for dark it is extremely oppressive and there really isn't any switchins to +2 tera dark wicked blow or surging strikes but apparently for the home meta 322 speed is too slow
not much I can say except its easy to revenge kill with faster stuff BUT
I do think that they require a suspect because not everything is confirmed yet
and if the zamas are staying (hopefully they are tbh) then urshifu won't be too much of a problem since from experience zama-c takes 60 from +2 tera water surging strikes and im sure wicked will do less
other answers such as Tauros water is amazing too since it kills 2 birds with 1 stone in correlation to walling Chien pao and urshifu at the same time with intimidate and great typing
just use faster mons or booster energy
if anything its arguable that rs is better than single rn since its offensive typing for the meta RN is better considering the amount of fairy spammers and zama c and magearna's literally everywhere
Alright, let's see how many of those faster mons can tank priority from the Shifus, and we may as well go +2 Life Orb Tera because you left that option open with the Swords Dancers:
Enamorus
252 Atk Life Orb Urshifu Sucker Punch vs. 0 HP / 4 Def Enamorus: 99-117 (34.2 - 40.4%) -- guaranteed 3HKO
+2 252 Atk Life Orb Urshifu Sucker Punch vs. 0 HP / 4 Def Enamorus: 199-234 (68.8 - 80.9%) -- guaranteed 2HKO
+2 252 Atk Life Orb Tera Dark Urshifu Sucker Punch vs. 0 HP / 4 Def Enamorus: 265-312 (91.6 - 107.9%) -- 50% chance to OHKO
252 Atk Life Orb Urshifu-Rapid-Strike Aqua Jet vs. 0 HP / 4 Def Enamorus: 114-136 (39.4 - 47%) -- guaranteed 3HKO
+2 252 Atk Life Orb Urshifu-Rapid-Strike Aqua Jet vs. 0 HP / 4 Def Enamorus: 227-269 (78.5 - 93%) -- guaranteed 2HKO
+2 252 Atk Life Orb Tera Water Urshifu-Rapid-Strike Aqua Jet vs. 0 HP / 4 Def Enamorus: 304-359 (105.1 - 124.2%) -- guaranteed OHKO
(252 SpA Choice Specs Enamorus Moonblast vs. 0 HP / 4 SpD Tera Water Urshifu-Rapid-Strike: 360-424 (105.5 - 124.3%) -- guaranteed OHKO)
Enamorus can tank Sucker Punch unless it's +2 Tera Dark LO, and she has a 50% chance of falling in that case. It's a similar story for Aqua Jet, except she guaranteed falls to +2 Tera Water LO.
Iron Valiant
+2 252 Atk Life Orb Tera Dark Urshifu Sucker Punch vs. 4 HP / 0 Def Iron Valiant: 108-127 (37.2 - 43.7%) -- guaranteed 3HKO
252 Atk Life Orb Urshifu-Rapid-Strike Aqua Jet vs. 4 HP / 0 Def Iron Valiant: 94-110 (32.4 - 37.9%) -- 95.8% chance to 3HKO
+2 252 Atk Life Orb Urshifu-Rapid-Strike Aqua Jet vs. 4 HP / 0 Def Iron Valiant: 187-220 (64.4 - 75.8%) -- guaranteed 2HKO
+2 252 Atk Life Orb Tera Water Urshifu-Rapid-Strike Aqua Jet vs. 4 HP / 0 Def Iron Valiant: 250-294 (86.2 - 101.3%) -- 6.3% chance to OHKO
Iron Valiant performs quite well against both Shifus: Sucker Punch is an obvious joke no matter how boosted it gets, while Iron Valiant has a slim chance of being OHKOed by Jolly +2 Tera Water LO Aqua Jet. Again, though, this emphasizes how paramount not switching Iron Valiant into attacks is.
Walking Wake
252 Atk Life Orb Urshifu Sucker Punch vs. 12 HP / 0 Def Walking Wake: 161-191 (47 - 55.8%) -- 78.5% chance to 2HKO
+2 252 Atk Life Orb Urshifu Sucker Punch vs. 12 HP / 0 Def Walking Wake: 321-380 (93.8 - 111.1%) -- 62.5% chance to OHKO
+2 252 Atk Life Orb Tera Dark Urshifu Sucker Punch vs. 12 HP / 0 Def Walking Wake: 429-507 (125.4 - 148.2%) -- guaranteed OHKO
+2 252+ Atk Life Orb Tera Water Urshifu-Rapid-Strike Aqua Jet vs. 12 HP / 0 Def Walking Wake: 68-79 (19.8 - 23%) -- possible 5HKO
(244 SpA Choice Specs Walking Wake Draco Meteor vs. 0 HP / 4 SpD Tera Water Urshifu-Rapid-Strike: 462-544 (135.4 - 159.5%) -- guaranteed OHKO)
Walking Wake obviously tanks any boosted Aqua Jet but is already at risk of being OHKOed by +2 LO Sucker Punch. Urshifu-S Tera Darks to seal that OHKO.
Meowscarada
+2 252 Atk Life Orb Urshifu Sucker Punch vs. 0 HP / 0 Def Meowscarada: 199-234 (67.9 - 79.8%) -- guaranteed 2HKO
+2 252 Atk Life Orb Tera Dark Urshifu Sucker Punch vs. 0 HP / 0 Def Meowscarada: 265-313 (90.4 - 106.8%) -- 43.8% chance to OHKO
+2 252+ Atk Life Orb Tera Water Urshifu-Rapid-Strike Aqua Jet vs. 0 HP / 0 Def Meowscarada: 168-198 (57.3 - 67.5%) -- guaranteed 2HKO
Meowscarada tanks boosted Aqua Jet quite well but risks being OHKOed by +2 Tera Dark LO Sucker Punch.
Greninja
+2 252 Atk Life Orb Urshifu Sucker Punch vs. 0 HP / 0 Def Greninja: 207-243 (72.6 - 85.2%) -- guaranteed 2HKO
+2 252 Atk Life Orb Tera Dark Urshifu Sucker Punch vs. 0 HP / 0 Def Greninja: 276-325 (96.8 - 114%) -- 81.3% chance to OHKO
+2 252+ Atk Life Orb Tera Water Urshifu-Rapid-Strike Aqua Jet vs. 0 HP / 0 Def Greninja: 173-204 (60.7 - 71.5%) -- guaranteed 2HKO
(252 SpA Choice Specs Greninja Hydro Pump vs. 0 HP / 0 SpD Urshifu: 346-408 (101.4 - 119.6%) -- guaranteed OHKO)
(252 SpA Choice Specs Protean Greninja Grass Knot (100 BP) vs. 0 HP / 4 SpD Tera Water Urshifu-Rapid-Strike: 626-738 (183.5 - 216.4%) -- guaranteed OHKO)
Greninja similarly tanks boosted Aqua Jet and +2 LO Sucker Punch reasonably well, but it gets OHKOed most of the time by +2 Tera Dark LO Sucker Punch.
Tl;dr: While the Shifus can be contained as long as they cannot get up a Swords Dance, one wrong move and a Shifu who Teras claims both the sacrifice and sometimes the prospective revenge killer that normally outspeeds.
