I just bought Mirage and Gnaw thinking I got two good deals but thanks the Krayt I found that I wasted money on buying KO's where I could have spend that money on getting something better and original. But the upside is that I might use part of Mirage's box and use that for my original Mirage.
On a side note I thought Mirage might have been a KO because I had heard about them before and I didn't listen to the nagging little voice in my head but I didn't know until Krayt pointed out that Gnaw had been done as well.
So a big thanks to Krayt for giving me the pointers on the KO's.
