First let me clarify the rules so that the question is understood: You are allowed 3 of any card that does not have a limit (e.g. Donald Lvl 1). Cards that have a limit are restricted to the number specified (Oblivion [Limit 1]). Magic friends with a limit apply to all levels of that friend (Simba Lvl X [simba Limit 3]). Genies level 1-3 do not have any limit, and you are therefore able to put three of each of these leveled Genies into a deck, however Genie Lvl 4 has a [Limit 1] that does not specify Genie.
If you put a Genie Lvl 4 into a deck, are you still able to use up to three copies of each other Genie, or does his [Limit 1] apply to all Genies you may have used, and therefore must play with a total of 1 Genie (the Level 4) in the deck?
