A favourite deck. The cards are great, thinner and lighter than average, with great handling as expected from Theory11. The fancy embossing is no surprise, present on the tuck cases, although the card backs themselves don't have an embossed appearance, just great design and colour.
The card faces are interesting, making another great themed deck. This suggests ideas for magic tricks that are often lacking if bored by using simply 4 Aces and a Joker as the key cards. By using the red deck too, you are set for a Chicago Opener magic trick if you're into magic. If into Maths or Self-Working magic, the card character names could be handy. But the character graphics are great, standing out by themselves. Great for a collector. A must have for anyone interested in the Avengers themselves, or anyone mad on the art style.
Most important for me is the price vs longevity & durability.
One deck of these cards is more expensive than an el-cheapo bulk-buy deck that can die in minutes, hours, or days, but with fairly regular use I got 6 months from a deck of these. The card stock is nice: cards spread evenly, with no clumping, all that time. Despite being thinner than some cards (a pro if that's your preference), they are expertly made to avoid problems with durability. The graphics printing is top notch.
The price is great for what you get. The cards are probably too good for regular card game use, overkill if not purchased for the graphics content. For handling alone, they are almost the best cards I've handled. They remind me of some other Theory11 decks that also have great handling, longevity & durability, but have an edge on others from the same company. They also have a worry-bead handling effect, like other well-made decks.
