Add 3 copies of utopia double, for some reason i wasnt able to add it when i was making the deck but you must add utopia double for the otk to work
Utopia otk is simple, spam level 4s, XYZ into utopia double, utopia double eff to add a double or nothing then utopia double also lets u xyz in utopia, (that utopias attack becomes 5000 because of utopia double) then use utopia to attack, utopias eff to negate its own attack, then double or nothing to give utopia 10000 attack, then attack for game (hopefully) the monster you attack must have 2000 or lower attack points to otk)
