hey, not really. this version is fast and guldan is slow. rin can't be used in a zoodeck. i recommend you to keep the deck as it is.
also i think you need to gain better informations about archtypes. the fact that you are suggesting rin tells me you are new to the game and are not familiar to different archtypes of hearthstone and how they work.
here you can learn about different and popular archtypes, how they work and what are the strength and weakness of them:
just make sure to click on view deck to see the archtype explanation.
