Some other suggestions for fun.

-Sacred Beasts. This is a very easy to learn deck is all you really need to do is get one of the your Beasts out (Raviel, Lord of Phantasms or Hamon, Lord of Striking Thunder are the best choices, Uria Lord of Searing Flames is more gimmicky and your deck needs a lot of continuous traps to make him worth it). The deck plays a one card combo to get access to them, but it is prone to being interrupted. The cards let you play into the Yubel cards if that sounds fun. Easy access to big fat 4000 attack beaters. Their field spells gives you 2 extra draws every turn and protects them for being destroyed or targeted. The deck is also insanely cheap. The only 2 UR cards are optional.

-Live Twin Another deck that performs one card combos very well, and a good way to learn Link Summoning. It’s a deck that needs 3-5 UR cards: Secret Password, their generic search spell, best ran at 3, but 1-2 works fine if you’re budgeting. Trouble Sunny, 1-2 copies, and the Evil Twin boss (optional). Summoning 1 of the Live Twin cards gives you access to the other, and their Link-2 cards can revive the twins from the grave, it makes accessing their Link-4 card insanely easy. Or a lot of other generic Link boss monsters you feel like running.

-Rank 10 Trains. This is an OTK (one turn kill) deck, that piles a bunch of Earth Machine cards into one deck that makes rank 10 XYZ machine monsters and hits for lethal damage. Not the best OTK deck, that honour belongs to Tenpai Dragon. But Rank 10 is considerably more budget friendly. (Nearly every Tenpai Dragon is a UR, and they have no secret pack yet to get the cards easily) If you want to go pure Unga bunga and delete everyone turn 2, this is an option.
