I recommend you to took out some movement
1 is very good on almost any map
2 is very good on some map
3 is only kinda good on crossfire
i also recommend you to:
-took out the "eject" and use some enlist or buffed unit instead, eject is good but on constructed there's many more better card than that
-took out the debuff "blind air" and just bring the temp one, those works more wonder in my opinion, i recommend using "blind any" instead, more versatile for any situation
-took out the air movement "aviation octane" unless you had some card to combo with it, combining it with mercenary feels kinda wasted in my opinion
-include some vision card, it will be pretty fatal i think
-for the all mercenary strategy to works better you might need "i need reinforcement"
Judging from your deck composition i take it the main strategy is mercenary rush right?
The main vulnerability of that strategy is that it practically not good for a big map since by the time your mercenary already come, it's time is already near the end
The other vulnerability is that if you does not bring any permanent unit along with the mercenary, then it will be "then there were none" all over again, at the beginning it's crowded but by the time 5 turns out, both you and your enemy units all gone
