What is a good theme for a Yugioh deck?
Here are some good well structured themes that I like/run, although some of them would cost a lot: Crystal Beasts (the best in my opinion, my friends brother got a rainbow dragon for $7AU off ebay, which is really cheap). Elemental Heroes (really easy to make, and very strategical) Dragon (you might want to try a basic dragon, or dragon lockdown, maybe even a Horus, cyber dragon, BEWD, or a red eyes theme, they’re all really good) I love the Horus and the Armed Dragon decks. Spellcaster (there are lots of different spellcasters to put in a deck, and most of them are really easy to get) Zombies (really good to run) Hope that narrowed your choices down a bit, good luck.
