The strategy is very simple:
search for gagaga magician and use cards like onomatopoeia to just summon it and with some other cards, like onomatopickup, you can make all the levels on the field like gagaga magician's so you can summon photon strike bounzer, then zoodiac chakanine and then zoodiac drident. Then, if you can, just summon utopia double and utopia kaiser. This is the strategy.
