Probably fantastical, but I'd love to see this sort of a stadium-
Somewhat of a MagneStadium, but those with magnetic walls and exits, and not the one which we have already(magnets in the play area. I know this can be done by placing the magnets of the current MagneStadium near the exits and the walls of the stadium, but I am speaking about keeping them right outside the circular play area, that is, in that small octagonal strip beyond the circular area)!
Most importantly, the magnets of the walls and that of the exits should have opposite poles up. That is, if the walls have the North Pole up, then the exits must have the South Pole up(and vice-versa)!
Whenever the bey goes close to a wall, should it repel, then it'd fly right into the center! That would provide for a powerful Attack!
Aaand, should it attract, the bey will bang into the walls!
Now, if the bey goes close to the exit, should it repel, then it'd take a hard time KOing it. But once you do manage to get a strong attack, then it'll go on to the other side of the magnet, and the repulsion would kick it out of the stadium instead of keeping it in.
If it attracts, the opposite would happen. If it goes close to the exits, then it'd be attracted towards the exit. And if the beyblade is moving with a relatively higher speed and the magnets aren't strong enough, then due to inertia, the beyblade would fly out of the stadium (even without being touched by the opposite bey, at times!)
And if the beyblade is moving with low velocity (after being hit by the opposing bey; in a position wherein your bey would have been KOed under normal conditions) towards (and eventually out of) the exit, then the magnets would attract it, and keep it from being KOed! And who knows, if your beyblade has enough Stamina, it can stay out there at the edge and outspin the opposing bey! XD
