Cost lowering Serra+Beast

I'm new here and probably you know this method but I wanted to share. With a little luck, play sunspot/antman at first/play nothing. Then Okoye/Witch/Angela. Lizard can be used to troll opponent later. Third turn Bishop/Nakia. Fourth turn comes Beast to reduce cost for all cards at one location. Next is going Serra and one of cards you reduce cost earlier. At this point majority of cards should cost 0-2. Full one location using Angela, if it's possible to place Strong Guy somewhere and get additional power if deck is empty. Also Titania is awesome if a location is full on the opponent's side. I won majority of matches with this method, even won (what a surprise) with Wave which has trolled me in the past.
