Actually, ANY move that has variable damage can be risky. for an encyclopedia of such moves, see below:
Acrobat: must not have an item to be usable, which is risky.
Assurance: you must find a way to damage the target before Aurumoth moves.
Avalanche: does more damage if Aurumoth is damaged on that turn, assuming it can take the hit.
Bide: REALLY dangerous; in order to use this, Aurumoth must be damaged AND survive for two turns.
Brine: doubles damage on a target with less than half its hp left.
Counter, Mirror Coat, and Magic Coat: require proper timing and prediction.
Echoed Voice: must be used consecutively.
Electro Ball: must be used on an EXTREMELY slow target to be effective.
Facade: Aurumoth must be suffering from status for this to work.
Flail: does more damage when Aurumoth is at low health (if it doesn't get KO'd first).
Fling: requires a specific item, usually with negative effects.
Foul play: is only effective against high powered sweepers, who very well could KO Aurumoth before it has the chance to act.
Heat Crash / Heavy Slam: ...Um no, Aurumoth is WAY too light.
Hex: Does more damage to targets with status.
Ice ball: doubles power every turn, but locks user.
Low Kick / Grass Knot: only works on heavy targets.
Natural Gift: requires Aurumoth to use berries.
Psywave: deals random damage based off Aurumoth's level (lv 100).
Punishment: does more damage if your opponent has more boosts (or this boosted pokemon could just sweep your team.)
Pursuit: doubles on fleeing pokemon.
Retaliate: only works effectively if a teammate has just been KO'd (can be used to revenge kill).
Revenge: doubles if Aurumoth has been damaged on the same turn.
Reversal: works effectively if Aurumoth is at low health.
Rollout: doubles power every turn, but locks user.
SmellingSalt: doubles on paralyzed target (but removes paralysis).
Stored Power: the more Aurumoth boosts, the better this is.
Trump card: the more it's used, the more damage it does.
Venoshock: hits poisoned targets for double.
Wake-Up Slap: doubles on sleeping targets (but removes sleep).
