Tribute summoning this card plus normal summoning it the next turn might be a little slow to get the full potential effect of this card. However, once achieved, the effect will provide a great support for your Red-Eyes Black Dragon.
Why is everyone trying to hate on Konami for this. They are experimenting with these kinds of thing, this is the first time this kind of event has happened. The yugi event was the only one that wasn't up to par with the other ones was because of the RNG. Other than that this game has only been out for a couple of months so cut it some slack.
Got four dices, lots of R and N cards, but not even a single one of those I want. I've been beating Joey lvl. 40 consistently for 6000-7000 DA, and nothing. I can't complain about the spawning rate, and he appears almost always as lvl. 40, but unitl now, that's useless hahahahha.
