How to increase health

I’m at a point right now where I can max out health and regen in the first ~1500 waves (I have the wall and it’s going well) but after picking the 1.98 trad off and the x8 regen/-60% health I only got about 300b hp left (with max devo)

My lab is at 2x health Common and rare cards are maxed Enhancements are at x1.20 health

Am I missing something besides lab and enhancements? Because I’ve seen people who have about 1.7T health left after picking the trade off perks. Pls help:)
