What can i replace Rin with ?

if youre looking specifically for defense, put in a tar lurker. you can also tech in weapon destruction such as an ooze or harrison jones

Only missing krul for this deck.. and it's the card rotating. Rip

We really need  Krul the Unshackled for this deck or ?

tbh you could use skull and be the same, the heavy demons arent in this deck so krul is just in there since hes part of the highlander set. but if your not running krul, might as well play control lock

i am not quite sure about master oakheart, it let me down quite a lot.

It's tricky because he can pull Kazakus, which you obviously don't want. 

id say give it atleast a couple days, id even wait a week it sucks to waste dust on stuff thats only used for a short time. your choice tho
