It would be a UR from a big box if Konami decide to release it. Its effect is ridiculous and it is also very easy to summon since all Paleozoics cam be summoned as WATER monster
Wouldn't it be better to give Zero as a lvl-up reward for Jaden or as an event 1-off card?
I understand and I agree with what you are saying, that Zero s effect is stupid, but putting him in a box is even more dumber, because some players will have access to 3 copies of him, while the others only 1 or none.
Plus, just by combining it with Sea stealth attack or Dimension Gate you re opponent looses his entire board with no cost.
I know is brickie, but Konami will release future boxes more powerful cards than those, and by having access to just one copy of Zero, you don t need to hit those respective cards.
