Hello!
After reading this : viewtopic.php?f=59&t=103221 (Shadow Dragon vs Egg of P'an Ku) - I still have my doubts.
1) "Copy" (noun) is a reference to particular piece of game. Not a reference to a result of "copy" (verb) effect. All Ikoma Whathisname in deck are refered to as "copy of Ikoma Whatisname", but neither of them are a copied instance of another I.W, and neither of them ever copied another one. (#Copy_.28verb.29) 2) "Create a copy of card" effect does not copy (verb) a card. It creates another instance of "the card" to exist in game, with all of its text and stats "imprinted" already, and considered "base". (#Creating_cards - 3rd paragraph, #Base)
Then, again, what happens if "Create a copy of a card" (for example Egg of P'an Ku EXP) meets "ability will not be copied" (for example Shadow Dragon EXP - but I am inclined more into Asako Usohara)?
