Ace in the Sleeve (53 attack, 23 defense) is an item now available in Mafia Wars.
To get this item, simply install the Zynga Poker App and get to level 6 (in poker). About the best way to do this seems to be to just get into a 1 round tournament and play.
String of Firecrackers now has 46 defense. This is the reward from the Mystery Bag Collection.
There are two new free gifts: Zip Line (vehicle; 15 attack and 20 defense) and Hyena on Chain (weapon; 20 attack, 16 defense).
There's not much else going on in the game right now. St. Patrick's Day is coming up, so expect an in-game holiday event soon!
