In my case I replaced one Spreading Plague with one Sea Giant. I found that Spreading Plague doesn’t often get it’s potentially incredible value. If you’re dominating the board it only gives you one harmless taunt body. If you’re struggling to re-gain control or are behind, it’s a nice safety net. I often lost anyway in this case, because 6 mana is expensive and it really only slows your opponent down a bit. Depends on what you want to emphasize in your deck maybe.
