Striped Bird was added in Beta 30.0. Previous Versions can be found here.
Striped Bird is a strange card. At first, it's a very decent 4/5 4G Haste monster. But after it has attacked (and every time it attacks afterwards), it paralyzes itself. It also lacks any other effect, making it very weak and only able to attack every other turn.
This makes it usable against a Patience player to redirect their passive effect, as well as a decent addition to a deck featuring Ball Person. (Just keep in mind to attack before playing Ball.)
