simgari ^
and mabe you should have 4 bioshifts

check corpsejack menace rules with bioshift rules they work well together
for every corpsejack you double +1 counters because the ability stacks so with 2 corpse on the field you would add x4 that many counters if you have 3 you would add x8 and 4 y ou would add x16
also i would consider droping the zegana's as there legandary and with corpse could easily deck you out. nimbus swimmers are a good replacement because the counters will double as it comes into play or primorial hydra

You should put some vexing devils in here and some legion loyalist there good 1 drops the vexing will deal a good ammount of damage and loyalist are a great 1 drop as well

also i would add one more silverblade there really good

sorry i was looking back over this deck and i noticed that your running it mostly humans in that case i would still say to add the vexings but legion are not humans :/ vexing is still a good 4 damage shock for 1
