I have over 30 decks. I might have even more, as I've discovered more while storing them. All of them are double-sleeved, with soft inner sleeves and hard outer sleeves for maximum protection. I have both leather and plastic deck cases. I have a playmat of Evil★Twin and one of the Magician of Bonds, which was only sold at the 25th Anniversary Tokyo Dome event. I think the sleeves of both playmats are used in some decks. Regarding the Evil★Twin deck, the sleeves are from YCSJ and match the playmat. Lyra-Lyrical is also included in the deck. I also have a collection that was displayed as a display. I have an opened 25th Anniversary Psychic End Punisher structure deck, but the deck cards themselves are unopened, only the bonus packs are opened. Old cards are in a storage box. There are also generic cards like Ash Blossom & Joyous Spring, Maxx "C", and Pot of Desires. The Rare Collector's Box is shown, but it only contains cards that didn't fit in the storage, so please be aware of that. -Deck List- Sacred Beast Manadome Eldlich Zombie Exodia Vendread Dragonmaid Kashtira Evil★Twin Traptrix Train Ninja S-Force Amorphage Rikka Spright Crystal Beast Kaiju Power Tool Tearlaments P.U.N.K.

I don't really remember when I started playing Yu-Gi-Oh!, as it was when I was a child. But I remember when I won Blackwing - Vayu the Emblem of Honor at a card shop, a big person offered me a shark trade, and when I refused, they forcibly took it and I cried. They ran away after I showed it to them. I started around that time. Probably around the 6th generation. Unrelated, at the 25th Anniversary Tokyo Dome event, there was a corner to duel, and I faced the user of the Self-Destruct Switch deck. To explain, it was a knockout tournament where you were eliminated after two losses, and a draw was considered a loss. In other words, it was a sophisticated harassment. I will not forgive the Warrior of Love.
