ok so i'm getting rusty and i'm trying to remember if when a card says to commit a foundation, if you can commit any foundation anywhere, as in your opponents staging area, unless it is a cost. To give some sense to that Detached's R: reads:
R Commit: After you take damage from an unblocked attack, commit 1 foundation and discard one of your opponent's momentum.
now my question is can i commit an opponents foundation? It doesn't say "any foundation" or "your opponent's foundation" like it does when you normally can.
