The current item description for TMs in PMU is currently just ‘‘teaches you the move X’’, which is not very helpful when selecting movepools.
This description space could instead be used to describe the actual use of the move in the form of short descriptions, for example:
Teaches you the move Flamethrower.
A ranged fire-type line move that hits all targets within its reach.
Now, while Flamethrower is an obvious one, there are many moves (e.g. Ally Switch) that aren’t very straight forward and would benefit from a description. Format of these descriptions would of course have to be decided beforehand.
This would be especially helpful since not all moves in PMU work the same as in the mainline games.
