These were the GB cards everyone wanted, but nobody wanted to buy what felt like an "old" game at the time
The cards in this deck are not particularly rare and they're not random, like a pack of cards
Take a look: When you split up the Dot Code part of the card into what they would look like under Red, Green and Blue light well, you clearly get some different examples of what they look like: The blue view lol, nope The green view a little better, but some of the stray printing it might interfere with the e-Readers ability to read the Dot Code bar properly The red view now THAT is a nice clean pattern
Certain cards will entirely lock you out of other summoning mechanics, and the fusion monsters were created in a period of Yu-Gi-Ohs history where they only had to do the bare minimum to be considered good
By turn five, you can expect to be cheating out huge mana-value creatures, like Demon of Death's Gate or Pestilence Demon
