Overruled rule

[badganondorf]

So this is the ruling I'm talking about:

== CALL FOR FAMILY (Exeggcute - DP:Legends Awakened; Plusle - DP:Majestic Dawn; Eevee - DP:Majestic Dawn; Chatot - PL:Supreme Victors; Others)

Q. If my bench if full can I still use "Call for Family" to search my deck?
A. Yes, you could search your deck, but not put out any Pokemon. (Supreme Victors FAQ; Aug 27, 2009 PUI Rules Team)

***** PREVIOUS RULING: THIS ONE HAS BEEN OVERRULED; See Above *****
Q. Can I use "Call for Family" if my bench is full just to look through my deck?
A. No, you cannot use Call for Family to search if your bench is full. (Jul 17, 2008 PUI Rules Team)

So can I search my deck if I use Call Energys effect? It's the same effect as CFF.

How about Great Ball, can I use it even if my bench is full? It's not exactly the same effect but still pretty much the same.

Thank you in advance.

Call Energy, yes.
Great Ball, no.
Why the difference?

Because with Great Ball you would be playing a card when it is known that it will have no game effect.
For the other two, you are using effects or attacks of cards that have already been played.
