needs wryms, perhaps add in 2 or 3 of them. Also 1 shortbow should do just fine, two will just clog your hand. So my take on this is -1 shortbow -2 towers, +3 wryms since your relying just on dragons since flies don't help much a second attacker will defenitly help. Or maybe replace the flies with wryms since the new AI with dispose of them quickly.
It's rare that you draw both Bows in one game, and 7 damage for 2 quanta in insane to have, very much worth the extra card slot in my opinion. The Damselflies are actually just meant as CC-absorbers that also function as Pillars and do a very light amount of damage.
I've tried using Wyrm's and I honestly believe Dragons are better: You get some more damage, no additional quanta drain, as well as 7 hp, which is more than enough to ensure it doesn't die easily to the new elder's CC, compared to the Wyrm's lesser damage, upkeep cost to retain that lesser damage, tiny 3 hp that gets wiped out by pretty much anything, and what, 8 less static cost? maybe 4 tops, assuming you only Dive twice, and getting it out first turn (Not unlikely considering you have 16 Towers with my version) means you're probably going to have to Dive it 4-6 times, causing it to be more expensive than the Dragon, for zero benefit.
Just my take. You are of course free to experiment with Wyrms, it'll be interesting to see how the ttws compare.
