-2 nova (4 nova = 48
, 18 shard = 54 and you can get extras from mark / pend)
-6 death pends +4 death towers (you only need 1 light quarta / turn, and you don't need 6 towers for just poisons)
^ are what I would think are requirements
reduce number of some of the shards. I don't think you need 20+ turns of protection (12 Sosa, 6 sundial, additional from SoD+Sosa mix). You can do 15 damage by the time you have half your deck out on the board, and even more as the game drags, so try to reduce the card number more to 35 or so.
