So far the most powerful creature I get by combining cards is the "Twin-headed thunder dragon", a monster that happens to be a fusion type, it has 2800atk and 2400def, but I think if I use "Umi" or "Mountain" it could raise its points to 3300atk and 2900def, I could also increase the points of "Mystical Sand" up to 3100atk and 2700def with "Wasteland" and an equipment card that looks like a female armor but I forgot what it's called, coincidentally I just found out that it is also a fusion type card haha, I still can't get something more powerful than the "Twin-headed thunder dragon", I'm going to do a little research to see if there is another more powerful one that I can create.
Thanks for stopping by and commenting.
