@bepoest, imho, you’re using too much swarm finishers without actually producing enough swarm. Giving up Jammers may be a good decision, since you don’t need to last later than 7 mana, inkling should be enough. Without hard removal you’re not prepared for late game anyway.
@duzt, the problem is that you have no early tempo. First of all, you have a pretty low quantity of early plays and not so much efficient removal. If you lose initiative too early there’s no chance ANYTHING of yours sticks. And you WILL lose initiative, since only 2 of 7 of your early minions (mystics) have decent stats.
Think of more oppressive early game. That way something may stick later. Ooz, Primus are nice 2 mana options, while Tahr is a monstrous 3 mana one.
