Yu-Gi-Oh! Deck Is Built Entirely from Stuff I Picked Up

So the true essence of Yu-Gi-Oh! is actually scavenging through trash heaps and back alleys for cards? I've transmigrated into the world of Yu-Gi-Oh!, and now there's an immediate problem: How is a complete nobody with no identity, no money, and not even the ability to speak the language supposed to survive in Satellite, the slum district of New Domino City in 5D's? As everyone knows, in Yu-Gi-Oh!, everything runs on cards. So the obvious first step is to pick up a deck. Once you've scraped together a full deck, you can do anything. What's that? You're saying anything I can scavenge will just be a pile of completely ordinary cards? That's fine. Yu-Gi-Oh! is, after all, a trading card game. See that girl up ahead-Aki Izayoi? Let's go on a date with her, make her blush, form a bond of hearts, and then trade for Black Rose Dragon. And if romance sounds too difficult, you can always go find a bro instead. See that guy over there-Seto Kaiba? He's actually one of the easiest types to deal with. Beat him fair and square, and he'll latch onto you himself. With all the cards his money can print, as long as they're not Blue-Eyes White Dragon, you can get a copy of practically anything. What? That still sounds way too hard? No problem. Yu-Gi-Oh! is an inclusive game. There are still Duel Monster spirits you can win over. Take that Mermaid of Aqua right in front of you. Just run up, grab her leg, and call her "Mom."
