Bri Synchron-- when used in a synchro, the monsters effect is negated.. so.. using it for stardust or power-tool would only take away the stardust guard and the power in power-tool. it would only be useful with red dragon to keep red dragon from blowing up monsters on your side of the field that don`t attack.
Here is some help that you should take in mind and make changes if able as the deck would be more effective, as A good friend of mine plays pro with such a deck.. this is what come to mind form dueling hims all the time, so cards could be missing. but wala. ^^
