here's a quick little list of what you're looking at:
look of the deck
handling of the deck
how long the deck lasts
now i have had all 3 of these decks, and although i would say that split spades have a smoother feel, and last an amazingly long time ( i spread mine in snow.. and they are still amazing (i wouldn't recommend spreading cards in snow though, i just could because i ordered a ton.)) ANYWAYS, back on topic, split spades are an amzing deck of cards, then there is smoke and mirrors... visually appealing, the mirror deck looks amazing , definately my favorite deck for flourishing. I would pick smokes for magic, not because mirrors have black borders( it doesnt make much of a difference), but because they just come accross as more "natural" cards to perform with.
Bee stingers, i must say, i killed these rather fast, but while they lasted, they felt pretty good, i mainly am not a fan of the bee design however.
so now, overall i would recommend smoke and mirrors more, and mirrors more than smoke if you're going for: flourishing, smoke more than mirror if you are going for: magic
and both if you're looking to collect decks
Split spades are a great all around deck, so if u find yourself performing magic, but practicing flourishing, go for these, they do last really long, so you don't have to worry about them dieing because you practiced with them.
hope it helped
