Worth knowing
It cannot choose an event-exclusive attack outside the ordinary TM pool. Repeated uses can cycle through moves you have already seen.
Fast TMs do not affect Frustration because it is a Charged Attack.
Why several TMs may be needed
With four currently eligible alternatives and equal selection chances, a particular move has a one-in-four chance on each attempt. The average is four uses, but that is not a guarantee: after four attempts the chance of still missing it is (3/4)⁴, about 31.6%. This example assumes the same number of alternatives remains available.
Fast Attacks can also change a Dynamax attack
For an ordinary Dynamax Pokémon, the Max Attack’s type follows the Fast Attack’s type. A Fast TM can therefore change both its normal battle role and which type it attacks with during the Dynamax phase. Hidden Power is an exception: it produces Normal-type Max Strike.
Changing the Fast Attack does not erase Max Move upgrades. A Gigantamax Pokémon follows different rules: its species-specific G-Max Attack does not change with its Fast Attack.
