Remove cards from a deck

The remove flow is the mirror of building: instead of the whole card pool, it deals only the cards already in your deck.

The four swipes

A first-visit hint ("Swipe to trim") covers them:

• Swipe right to remove the card from your deck.
• Swipe left to keep it.
• Swipe up to move it between boards (to the maybeboard, or a maybeboard card up to main).
• Swipe down to undo your last swipe.

Boards, filter, and refresh

The Boards row picks the pool you're trimming: Main, Maybe, Side, or All. Filter narrows it further, and Refresh restarts the stack and clears your undo history.
