One group of people want this card, while another group of people says this card is too OP for DL.
Now that this card is in DL, where are those people???
Apparently none of the people who wanted this card ends up using it since CyDra is not meta at all, and if it's really as OP as the other group claimed, why are they not using it now that it's in the game?
The optimal version still needs at least one copy of OG Cyber Dragon. It is a Cyber Dragon in hand. The only card that Cybernetic Overflow can use directly from the hand, to help you destroy more cards your opponent controls.
And the more important is, it is still a Cyber Dragon when banished. Banished Cyber Dragon is great material for Cyberload Fusion. If you control a Cyber Dragon monster on the field, you can go for Cyber Twin Dragon. If you have 2, you can go for Cyber End Dragon. And if you have many banished machine monsters, you can go for HUGE ATK Chimeratech Overdragon
