* '''[[Card Rulings:Chimeratech Overdragon|Chimeratech Overdragon]]''': When you [[Fusion Summon]] this card you can use a [[Fusion-Substitute Monsters|substitute]], such as "[[King of the Swamp]]", for the "[[Cyber Dragon]]", but not for the [[Machine]]-[[Type]] [[Monster Cards|monsters]]. That means you can use a maximum of 1 [[Fusion-Substitute Monsters|substitute monster]] in the [[Fusion Summon]].

* '''[[Card Rulings:Generation Shift|Generation Shift]]''': If you [[target]] "[[Proto-Cyber Dragon]]" or "[[Elemental Hero Neo Bubbleman]]" with this effect, you must add "[[Proto-Cyber Dragon]]" or "[[Elemental Hero Neo Bubbleman]]" to your [[hand]]. You cannot add "[[Cyber Dragon]]"...
