They create the best natural cover for double lifts. I suggest if you are one of the people out there that struggle with having new decks available, grab yourself a black ghost deck from E. Warped cards are **** for packet tricks, and you don't want that to throw off your false counts or the fact you have an extra card. I can't believe I'm saying this, but BGhosts work phenomenally for packet tricks. It's because of the smoky edges, which throw off the stacked cards and make it impossible for a spectator to follow. Although this shouldn't be your aim to confuse a spectator, the cards will provide extra cover for i.e. Mercury (because I know SO many of you perform it, for some reason I know not and will never understand). If you're one of those black deck collectors, take a look at a nice DL from the BGhosts, and then compare it to that of a Tiger deck or Viper, and maybe even Split Spades. There is a significant vision ambiguity, and well... its exploitable. Just saying tho... it was an interesting observation. I usually would never even stoop to using black decks or anything besides a deck of red Bikes, but hey... it seemed interesting and I know some people on the forums were discussing benefits of Black Ghosts over other cards. Here's just another. Once again... I'm adamantly sticking to Red Bikes because a good DL doesn't REALLY need any cover or ambiguity. Sorry for the contrasting viewpoints in this rant, but yeah... i'ts sleepy time.
