Pyro

Axiom Discs says this about the Pyro:

The Prism Pyro is debuting with a stock triple-foil stamp, that in combination with a Proton core and Prism rim produces a stunning dual-toned translucent disc. The Prism Proton Pyro was designed as Axiom’s first overstable Midrange with more glide than the MVP Deflector and a commanding stable finish. The Pyro has enough stability for consistent flights in strong winds and powerful throws without losing its line and turning off target. Fire away with the predictably overstable flights of the Prism Proton Pyro!
