mekk knight deck yugioh Yu-Gi-Oh Card - EXFO-EN019 may be 1st or Unlimited Edition Yu-Gi-Oh: Yu-Gi-Oh! Day Mekk-Knight Playmat

Why you ask

Pokerev opened the pack at the 6:14 mark to see a reverse holo Magcargo, Qwilfish, Meloetta, Falinks, Snom, along with others

This is a 3-mana wheel that shuffles your hand and graveyard back into your library before drawing

That said, it's a much faster way to show a Trainer how many cards they're missing from each deck and booster pack

That being said, I think this likely ends up not turning on often enough to be worth it in actual play, or in the case of Domain the extra 1 damage isn't what you need, it's to remove the Leyline of the Guildpact

cards are in pixels, why you should not use Pokmon or MTG sleeves for Yu-Gi-Oh
