"¢ [Re: Proto-Cyber Dragon] You can use "Machine Duplication" and "Proto-Cyber Dragon" to Special Summon up to 2 "Cyber Dragons" from your Deck.
Also from RONINâ„¢:
Proto-Cyber Dragon
Effect Monster (Machine / LIGHT / 3 Stars / ATK 1100 / DEF 600)
This card's name is treated as "Cyber Dragon" while it is face-up on the field.
So, how is it that Proto-Cyber Dragon can be used with Machine Duplication since it's ATK is 1100?
