with 2 rats it will be okay?

You have a couple things that Rat could search, but very few things you'd want to search very often. It can grab Nimble, which will then grab the others. The only other decent target it the other Rat. Exiled and MSLV2 are possible options, but will rarely be useful.

im not crazy on the addition of stien in the deck. personally id run injection. its an earth monster so the rats will have something to search. plus if it gets through, it can change the face of the dual very quickly.

also. dont take out call. thats a must. its a great card to suprise your opponent with when he/she attacks. also its good to use at the end of the turn to get a monster back. plus it doesnt cost anything to use.

Stein is a no brainer in a deck with 3x Nimbles, 2x Exiled, and Last Will.

Call is bad.
