Let's get to it, yes?
Ajani, Mentor of Heroes took over the spot from Tamiyo. I only had one but it showed up in two different matches, against both Matt and Caitlin and it did a LOT better than I had hoped and while it might seem obvious to anyone-duh, making creatures bigger is a better thing-it works specifically in Knives because 1) my global removal still doesn't hurt me, no matter how big my creatures get, and 2) my inability to take out a problematic creature sometimes matters a lot less if I'm able to attack for four or more a turn.
In the pictured matchup, Ajani eventually appeared and helped me take down a Soul Sisters variant that I made and Matt was piloting.
Because Ajani shoves that tide back and it does so without creating more of a strain on my blue mana. Which brings me to another point-one I'm really happy about.
While I'm actually very pleased with the way the mana has worked out for me, especially since I tweaked a Botanical Sanctum for a Forest, Tamiyo was pushing a little hard on the availability of Islands that I might have. However, considering I am not running really expensive dual lands or fetches, my ability to get the colors I need has been consistent! I'm pleased with this result.
Unfortunately I only have one Ajani so for now, I need to stall. One more would be pretty helpful, although I have two slots. The Mentor of Heroes is around $14 a piece though and that's a little high. One more I can justify but two is a lot harder, so the third slot is going to be claimed by Matt's suggestion of Arachnogenesis.
