When this card was first announced everyone was quick to say it was broken, but I think the truth is that it's trying to give you an almost guaranteed success.
Your base skill is 5, which is great. But what if you draw a bless token? You probably just wasted your Eye of the Djinn on a test you were going to succeed on anywa-- oh wait! You can ready the Eye of the Djinn and get the bonus again next test.
But what if you draw a curse and fail? Bad luck. Wasted the Eye of the Djinn again-- hold on! Get your action back! The curse still punishes you a little, but the Eye of the Djinn will do everything it can to make sure you will get some bonus and security.
