@ Decal stacking Exodia is the worst possible thing I've seen. I haven't seen anyone do this to me since I've never a player who stacks in this type of deck. My cousin who made a test Exodia deck was able to finish me on his second deck because it had insane drawing power (about 20 cards drawn in his first turn). I know my cousins and friends wouldn't cheat against me so I let them shuffle their owns cards and what not. I just keep score of life points and who did what in said turn.
@ Rennie Mm, I remember in one of the abridged episodes, they made a joke about playing card games on motorcycles, and then a few years later 5D's came about which was quite funny to see. If there was any reason to watch 5D's it would be the synchro monsters and Yusei's crazy comebacks.
