It can also stop scythe and key combo pieces in the mirror and straight up win it.

I begin to dump PKs and they attempt to called by a PK name to stop my engine getting going and Crossout the Called by - resulting in an OTK. Or my opponent and myself get into a simplified game state. It's almost 100 certain that their opponent is going to be running Maxx 'C', so having Crossout to prevent it ending their turn is already big merit. Maxx 'C' is one of the reasons almost all of the decks in the OCG run Crossout. It's such a meta-warping card due to its sheer strength. There have been several games I have established my board, end of main, opponent attempts to Nib me, drop the crossout, and opponent scoops because they cannot out the board. The first thing that comes to mind is obviously Maxx 'C'. My Crossout targets include Nibiru, Lancea (Usually resides in the side), Called By, Scythe, and Dark Ruler No More. I play Phantom Knights and have built with it. I have found Crossout to just straight up win me games. The smaller theory is that TCG players are against running 1-ofs or cards they are afraid might end up dead. Want to be notified when it becomes available again Simply. You can only activate 1 'Crossout Designator' per turn.

My theory is that players haven't adapted to the specific building the card requires and believe they can just side the card in specifically for the mirror. Sorry Our Crossout Designator MP21-EN258 Ultra Rare is currently sold out. Declare 1 card name banish 1 of that declared card from your Main Deck, and if you do, negate its effects, as well as the activated effects and effects on the field of cards with the same original name, until the end of this turn. All our Cards fit perfectly in all Yugioh-Sized. Everyone was super hyped upon this cards release however, it has seemingly done nothing. High-Quality, Unique Holo Effect (Mixture of Ultra & Secret Rare). I thought this might be an interesting discussion.
