I took Matt's advice and added in three Simian Spirit Guides to Razorclaw.. I removed two Mountains and decided I wanted to go to 61 cards rather than remove another land. I went to three Spirit Guides in order to aggressive test the idea. If I just add one I'm afraid that I won't get the opportunity to see them in action and it won't tell me enough.
Tests against stonethorn let me do (a very little bit of) that.
The other two games were slugfests and I'm pleased to say that my compliment of Acidic Slimes and Wickerbough Elders were very effective in keeping me in the game, win or lose.
But. But. What I'm discovering is that this deck is very, very mana hungry. Five mana is what is needed to play cards like Acidic Slime, Mitotic Slime and Wickerbough Elder and I really want to be able to play them as soon as possible. I need more data to find out if I have enough land or if I just need to bite the bullet and cut one of my Slimes for another.
In the match after this, I played against Pod, and I lost because I couldn't hit 5 mana, even though the game went long. Despite having two Acidic Slimes and two Mitotic slimes, I sat and did nothing while stonethorn executed his plans. The Spirit Guide mana isn't a bad thing but I don't feel like it's the
problem either: I just didn't have enough land in two games.
That is a problem and it's not a small one but I need to know if it's a fluke.
