Fix faulty implementation of Mirko, Obsessive Theorist

[Ryuteshi]

There has been an error in the implementation of Mirko, Obsessive Theorist.

The rules text reads "[...] At the beginning of your end step, you may return target creature card with power less than Mirko's from your graveyard to the battlefield [...]."

The present implementation also allows to target creature cards with power equal to Mirko's.

Hi, is anyone looking into this already? If not, can I do it?
