Well you can just replace the portals with some other giant like frostwolf , more small stuff like knifejuggler or just replace some minions with carddraw, but I for my part do not have problems with portals, usually draw 3-4 portals per game as long as I get 1-2 Portal guys within the first 10 turns and if you ask me the portals aren’t really essential , just a nice way of killing of demons for the giant imps and keeping board control.

Knifejuggler seems like quite the good idea , still not sure what to replace but I’ll probably put it in.

Grim rally is too situational , use it in ausual zoo deck , but it doesnt fit here if you ask me.

The deck started out with frostwolf in it and as it stands there were simply too much gigantic minions in it and frostwolf seemed to be the worst of them up until this point , but you could surely switch it with another one. Cult master on the other hand is too situational, for it to work you need a bunch of minions to suicide on your turn and boardspace , would recommend 0-1.
