I would lead ursaluna bloodmoon + Smeargle with Calyrex ice and ape in the back, here’s why If calyrex doesn’t tera you can always kill it with annihilape, this lead pins both options, smeargle can always take both attacks allowing bloodmoon the room to remove an important target. This lead forces your opponent to play defensively with Caly shadow, it also beats the incineroar Caly shadow lead since if they fake out bloodmoon you can spore with smeargle and if they Tera blast Bloodmoon you can punish with annihilape, either way, you still have your strongest Pokémon, Caly Ice avamailable with either Bloodmoon or Smeargle and their Caly shadow is too threatened to setup. Your opponent is too threatened right now to attack with calyrex, so the sensible play for them is to attack annihilape with surging strikes and protect, you can punish this by swapping ape into Farig and setting trick room, knowing that they could lose the game on the spot if they play too offensively they are likely to play it safe, with farigiraf in and trick room up you can psychic noise shifu and tera Fire glacial lance. This breaks urshifu’s sash and gets big damage on Caly shadow. You should also tell your student to ADD A WATER RESIST!!!!!
