Card Ownership

Two distinct types of ownership govern every card on the board. Understanding the difference is essential for scoring, graveyards, and flip mechanics.

Deck Ownership

Deck ownership is fixed and never changes. A card belongs to the player whose deck it came from — permanently, for the entire game.

Deck ownership determines where a card goes when it leaves the board:

• When a card is destroyed (DEF reduced to 0 or by Remove / Firestorm), it goes to the deck owner's graveyard.
• When a card is discarded (hand limit discard or covered card you cannot afford), it goes to the deck owner's graveyard.
• The Resurrection ability can only revive cards from your own graveyard — your deck-owned cards that have been sent there.

Deck ownership also determines which player physically removes the card from the board and places it in their graveyard or removed-from-game pile.

Flip Ownership

Flip ownership is dynamic and changes during play. It tracks who currently "controls" a card on the board based on its facing.

• A card facing toward you (in its original orientation) is your flip-owned card — it counts as your point.
• A card flipped 180° toward your opponent becomes their flip-owned card — it now counts as their point.

Flipping happens when your arrows point at an opponent card and you win the conflict. The card rotates 180° and is now yours by flip ownership. The deck owner does not change.

Flip ownership can change multiple times in a single game. A card may start as your flip-owned, get flipped to your opponent, then flipped back to you.

Score Uses Flip Ownership

Score is calculated entirely from flip ownership: count each player's face-up monster cards in the main zone that are facing them. It does not matter whose deck the card came from.

This is what makes the flip mechanic central to the game — stealing an opponent's card with a well-placed arrow doesn't just threaten their score: it adds a point to yours while removing one from theirs.

Graveyard Uses Deck Ownership

Even if a card was flip-owned by your opponent when it was destroyed, it returns to your graveyard (as deck owner). Your opponent cannot Resurrect it — only you can, because Resurrection targets your own graveyard only.
