Miami Heat fans are seeking some old-fashioned voodoo vengeance on the Dallas Mavericks, TMZ has learned -- buying up voodoo dolls by the HUNDREDS ... to curse the Mavs during the NBA finals.
They're selling out like hot cakes ... but the owner of El Viejo Lazaro Botanica -- which hocks all sorts of bizarre religious supplies, including voodoo stuff -- tells TMZ, he has no idea which Mavs are being targeted by the hexes.
If they're not buying voodoo dolls, we're told Miami fans are turning to herbal remedies -- buying what are called "Paraiso" herbs to use in a bath.
According to the owner, you put the herbs in a bath, get in, then visualize what you want to happen -- in this case, a Miami Heat victory.
Lucky for the Heat, they probably won't need the extra help.
