Robot Duplicate

When using its ability, Robot Duplicate's base attack and life become the sum of the of target monster's base and temporary attack and life.^{[needs testing]}
Because of this, it has synergy with the various temporary stats givers, such as Potent Injection and Twelve Stars.
Note that this card can't target itself, as then for each time it used its ability, it will be able to permanently gain whatever temporary stats that it had at the time.
However, this combo was not totally removed, as it does not prevent it from duplicating the stats of another Robot Duplicate.
Its ability uses a Life Set, and so any life losses aren't counted as normal damage.
