To be honest, I was trying to avoid being too specific about what I think you should do and was just responding to your own idea about adding more removal, but now that I've taken a more serious look at your deck, I do have a lot of very specific advice, if you're interested in that, and Longstalk will definitely be a more effective choice if you do decide to follow my recommendations
That means that while we should add in Staff of Nin because it both helps with pinging and gives us card draw, we probably won't be adding in stuff like Goblin Sharpshooter
I dont see Bond of Insight seeing much play in Commander but it seems like it could do some nice work in this deck
Jedit Ojanen, Mercenary Strange to see a card that spits out forestwalkers, but I guess Jedit Ojanen, Mercenary pays homage to the other Jedit Ojanens in Magic
So the question is, how do you start collecting Pokemon cards
