Put this card into your Gauge face down, and put the top card of your deck into your Gauge face down.

CONT: During the guard step in your opponent's turn, this card may be called to (GC) as a trigger unit, and becomes a guardian with Grade 0 / SLD 15000.

I actually have one question for those who played Buddyfight, when you pay for the Gauges do you get to choose which Gauge to pay or is it LIFO like in Weiss?
