Our best bet against Entropy is probably our grabow. Nothing we've tried to far has worked, and at least nova prevents discord. We also like controlbows, but we can't use RT with unless you add some time towers/pends.
Against light, they probably won't be able to resist using something like Arsenaders or dune scorps. Either that or their grabbow again, which is probably unlikely.
I really want to say adrenavamps again. I /really/ want to. It just has to be modified to with control (lightning/LS) to avoid a situation like last time. I think making it bigger would probably hurt it too much, so something has to be taken out. Also, if you face something like what happened last time, don't wait for the combo. Just play it out.
I have no clue what to bring against Fire, maybe PU dragons+LS.
Also, I'd like to strongly disagree with giving up dragons this early. Giving up our dragons now would be a bad idea in my opinion, since once we start losing 30 cards, we'll probably regret it. We don't have enough attackers in my opinion.
