[gilenroid]

Hi, i have made a rainbow deck and it is working out about 60% of the time against a level 3. this is mostly a build power deck. what i mean when i say that is my monsters get stronger the longer the duel goes on. so, if anyone has any card ideas on whether i should add or take out some please reply and i will try it out. thanks a lot =) (My sign is time)
p.s. i am kinda new so don't make fun if the deck is terrible haha
