On My Mark could also be a completely new gimmick. Like for example if a tactician uses an Order skill and uses Skip, the momentum used for said skill is refunded.

Of course, on top of the duration being extended to 2 rounds.

But just the above seems enough as it is, really. On My Mark does have the potential to be something cool by itself, but not mandatory in a Tactician's arsenal, is my line.
