couple things I will comment on:
1. Kite flyer is not a strong draw card unless it is in a science deck (with synergy), then it kinda breaks even. What you really want to do is break down the cost
Cost - 3 brains, 1/3 body, and gravestone.
plants comparison - 2 sun fire pea is a 3/2 body.
I am not going to analyze further really, as in a vacuum, the kite flyer is a really bad card (in hearthstone terms, it is basically acolyte of pain). You need to put it in the correct situation for it to perform its functions. You need the science zombies to give it extra attack. Lurch for brain is a pretty huge waste on kite flyer unless you have drone engineer. The fact is this card needs so much support, that if you put all kinds of support on other cards, they will appear just as strong (i.e. teleport valk, and then lurch)
2.toxic waste imp is a super tech card that requires immediate attention. I think it is one of the best cards in the game, on the tier of tough beets, black eyed pea, and whack a zombie.
