I always recommend the B-98 God Customize Set. Has 4 beys, happening to make for lots of good parts. That's my #1 pick for anyone new to Burst. (You'll get 4 frames in that box, too, if that's worth knowing.)
It's just that 2 beys spin right and the other 2 spin left, so you need to make sure you have a launcher for it. Spriggan Requiem 0 Zeta in the B-100 box will give you a couple more parts and a decent LR launcher in one buy. Or a different kind of purchase to get you the necessary launchers is fine.
The Spriggan Requiem layer (the top piece, like the wheel in MFB, I guess?) is so good that it will be going up for discussion for possible banning soon, haha. (If not at least its most spammed combo involving it and the Bearing driver. Drivers are the bottom parts with the tip. And B-98 has Bearing in it, which is good for other combos, too.)
But yeah, Burst Beyblades have 3 main parts: layer, disc, and driver. God Layer System layers have what's known as a God Chip, which may or may not be built in. It's the little circle in the middle, and it can help with stability and adding weight.
The numbered discs can be combined with frames, as already mentioned. (I believe all non-numbered discs are standalone?) And Cho-Z has introduced the Level Chip, which can only be gotten in Japanese WBBA Events, as far as we're aware, and adds stability to Cho-Z layers by attaching underneath.

Cleaning up threads, lalala. But hey, instead of tagging directly for issues, why not use the report button? It's just better.
