You can try as hard as you want, but a set of adamantium claws are never going to spring forth from your hands. Nor will you ever be able to control the weather, fly, teleport or read someone's mind. The closest you'll ever get to being a real-life X-Men is mastering this set of steel throwing cards like Gambit, minus the fireworks and bō.
The $US25 set only comes with four cards -- the ace of every suit -- so you better make each throw count. Also, you probably shouldn't count on being able to slip these into a deck of regular Bicycle cards unnoticed -- even if they provide the perfect way to vent your frustration at losing a hand of solitaire.
