Reddit reviews Ultra Pro Magic/Pokemon/Yugioh Cards Deck Boxes, Set of 10 (Red, Blue, Green, Black & White)

You will be tempted to buy up big boxes of bulk. I was told I shouldn't, but I did anyway. I figured I could take what I got and make crappy decks, then buy singles to fix them up. While I got some cards that were useful, it was only a fraction of what I got.

Although the decks on this list are all standard legal, they are great for any casual player and are all around $20 each. I really liked this list from Core 2019, too. The M19-only decks are mostly around $10, so they should give you plenty of value.

You can also consider Card Kingdom's Battle Decks. These are non-standard legal decks that are specially made by Card Kingdom with an eye toward balance and casual play. Many of them are out of stock right now, but you should be able to find a few to experiment with.

For non-card purchases, I like these cheap deck boxes for new players to store casual decks (here's a 5-pack instead of the 10-pack). They'll fit nicely inside your bundle box. You might even fit two unsleeved decks in each box. If you want sleeves, KMC is a good value/quality proposition. If you're not too rough, Ultra Pro Matte (not Deck Protector) sleeves are good, too, and a bit cheaper. However, keep in mind the cost of sleeves versus the cost of replacement. I didn't start sleeving my cards until I started building my own decks with cards that had some value to them. Honestly, I'd stick to buying cards until you run out of room in your bundle box and need more storage.
