yugioh black feather deck Yu-Gi-Oh! - Cards for Feathers (DP11-EN020) - Duelist Pack 11: Crow - 1st Edition Dueling Heroes Yugioh Crow Hogan Blackwing Deck

The effect was immediate, as Yugi was without any of his strongest monsters against an opponent who ends up summoning the Blue Eyes Ultimate Dragon

Using Zoodiac Tigermortar s effect will attached Ratpier as an Xyz Material, thus setting up the combo to bring out 2 Zoodiac Ratpier again

For collectors hunting rare Yu-Gi-Oh

If you note down the contents of all the packs from a box, you have a good chance of seeing overlaps (not all commons in box apparently come from the same sheet, there are usually 2-3 stacks of commons getting inserted into packs alternatingly)

Again, such tweaking has happened with multiple cards so this card can come into existence easily
