Battle Strikers was a line of magnetically controlled customizable spinning tops.
The toyline was released in 2009[1] by MagNext Toys and Megabloks from Mega Brands.
Each player additionally has a device that fits over two fingers which can be used to manipulate the tops through magnetism.
The winner is the last player whose top is left spinning inside the arena.
The system was later updated to use a ripcord launcher with the magnet inside an extension, simplifying the game somewhat.
