This is the rare I got in my first LON booster. It like paralyzing potion but better. It's a great counter to Snatch Steal. Your opponent uses Snatch Steal on on of your monsters, you equip the monster with Mask of the Accursed. You gain 1000 during your Standby Phase, your opponent loses 500, and they can't even attack with the monster.

This card is too easy to counter, and most of the time monsters dont stay on the field longer than a turn or two anyway. You might get 1000 damage off before they tribute it or you end up destroying it on your own. This card would be good for a stall or a burn deck, but not much else. There are just too many cards that are better to use.
