Collection Availability Tracking Across Decks

When building a deck using my collection, Moxfield currently shows cards that I own even if all copies of that card are already being used in other decks.

I’d like an optional collection-tracking feature that considers cards currently assigned to other decks and displays how many copies are still available.

Example: I own 3 copies of Reanimate, of which 2 are currently used in other decks.
When searching for Reanimate while deckbuilding, Moxfield would show something like “1 of 3 available (2 in other decks)”.

This would help users who maintain physical collections and multiple decks keep track of card allocation without manually checking every deck. This could be an optional toggle so users who proxy cards or ignore collection restrictions can leave the current behavior unchanged.
