Stun Spore
Ice Beam
Razor Leaf
Body Slam
Rest
Substitute
Hyper Beam
These include all of the moves that fit the prompt and I could see being viably run on a set, being Ice Beam, Razor Leaf, Body Slam, Rest, Substitute, and Hyper Beam. Any other moves I think either do not fit (Blizzard breaks the Triangle MU) or would be covered in flavor/filler (Toxic, Aurora Beam, etc). The main contention point is Stun Spore. Stun Spore doesn't break the Articuno MU due to the presence of Agility, and the Pokemon has such poor Normal MUs that I think it would not overreach to have the option. It would also diversify its gameplan from simply being RL + Freeze, which I find desirable.
