Any recommendations
Idk much about the new ones (i think they're not as cool really)
For the OG metal series ones, you'll have to pay a lot to get 100% authentic ones so i recommend midfakes. Some cool ones are Ldrago's, since they can spin steal really well and rarely you can even win battles by just hand spinning them. Variares can switch between three different performance tips which is hella cool and Hades kerbecs is one of the most epic looking beys from that series.
