using double sided cards- clarification wanted
Hey, very new to GA, but relatively experienced in most card games, looking for a little bit of a rules clarification re: Double Sided cards
According to the rules I was able to read, I'm meant to use the actual double-sided cards in my deck, and not stand-ins or proxies- Would it be acceptable for me to print proxy versions of the alternate sides of these cards, just to prevent myself from having to de-sleeve the cards and rotate them?
For example, I have a copy of [Beseeched Fatestone] in my deck. When I transform it, would it be appropriate to place a printed copy of the [Daunting Panda] side of the card on top to represent that I've transformed it? Rules say I can use a copy of the card, but I would just like to clarify if I could use a printer paper copy or a proxy instead
