Camoclone, I've owned one at various times, but I was always too scared to hold on to it for any extended period of time due to how expensive it was.
I wouldn't necessarily say I hate the card--but I hate the fact that I can't play decks like Blastoise (which is one of the best decks in the format, in my opinion) simply because I'm not willing to shell out 500+ dollars on three cards. The effect of the card is very good for the game because it promotes the viability of Stage 2 decks, but when a majority of the player base has no access to that card (or isn't willing to shell out an absurd amount of money for it), it becomes absolutely terrible for the game. Right now, I just want to see the card rotate so I don't feel cutoff from decks that had to play it.
