okay, there are two kinds of stuck.
There is the kind of stuck where a tight fit creates friction, and causes the card to slide out a lot harder.
Theoretically, this should be overcome with a pair of pliers, GENTLY use them to get a better grip on the card, and you will find that removing it will be a lot simpler.
Then, there is the kind of stuck that we shall call a JAM. My fake Acekard had a window where the chip was, and it was a tight fit to being with. After months of usage, the sticker wore off, and gave way to a plastic edge on the front of the card. This caused a mechanical jam, where the card could not be removed unless you would push down on the plastic edge using a piece of plastic, or a game card or something.
now what i want to know, is what kind of stuck was your card, and what was the cause for your card being stuck.
