It took me awhile (extra few seconds) to realise what the AoS is, but that's about it that i am liking this deck so far. The seven diamonds in the sword, though not a neccessity because of the deck, is too subtle for my liking. Since you would include the pips, i thought it would be nicer to make it slightly more obvious somehow.
The back...nice motif but not suitable for a back design.
