This is done with only gate cards.I use the quicksand card and throw down my 300g haos griffon and automatically win the first battleI use the blinding gate card with my haos saurus 330g and win the second battleThen i throw down the lift gate card with my 600g ventus/aquos wavern boosting it to 970gs usually winning the game for me
If playing with friends this is fine, but by official rules you need one gate card of each color ( gold, silver, bronze ) and all 3 of these cards are bronze.
