I personally don't care about whether the current rulings state it or not, frankly 75% of the time i don't even look at them because they are so incomplete.
This is how it's always been ruled, and i believe the Netrepâ„¢ Files support it as well. It's really common sense since we know that
Gradius' Option cannot exist without a real
Gradius face-up, and must mimic one of them.
There is only one ruling that that seems odd ot me:
"[Re:
Skill Drain] The ATK and DEF of "
Gradius' Option", the ATK of "
Maju Garzett", and similar monsters is 0 while "
Skill Drain" is active, and is not restored even if "
Skill Drain" is destroyed."
As far as i can see, these are Continuous Effects, now if they want the effects to dissappear that fine i can see that, but then
Gradius' Option should be destroyed as the link was cut, or you should select a new one.
