# Infinite loop
When dueling against Axel, have a monster on the field that is the only one which negates effects targeted to its own type (for example, Cyber Phoenix). If the CPU has Tri-Blaze Accelerator or Blaze Accelerator out and selects the monster (Cyber Phoenix), its effect will negate Tri-Blaze/Blaze, and Axel will not discard a Pyro-type monster. This will continue in an infinite loop until you exit the game or turn off the PSP.
