Eighth Gate: Gate of Death

Target only Ninja.
Target Ninja gets +5/+0, Haste, and Trample
until end of turn.
At the end of combat, sacrifice the targeted Ninja.
This Jutsu so puts immense strain on the body. Ninja become exponentially more powerful, but they end up tearing their muscles and breaking their bones as they
fight. This Jutsu ultimately results in the user's death.
