1- It is decent for R5-R4 solo and might get R3 by end of season all depending of heat mechs in particular due to resist is low. If those are your modules availability so is fine till get some extra.
2- It is decent o play for R7-R6. The issue is sacrifice does eat HP ad using the wrong turn for it you will run out of life been low on HP. If you use those 2 at 2v2 can achieve R5 maybe more but will be an R5.
3-The last is looking good sadly it is too low on HP and sure will cross to R5 due to power but at R5 tuff guys will show up. Sure will get R4 depending luck and smart play. If that is all you have to make combinations due to modules limitations are fine to use as they are.
1- That it is a bit crazy. No way in the current format. Why? Low HP for weapons in use. Drone eat HP, Blaster eat insane HP and sacrifice eat HP. If you do 3 shots even getting an attack you killed yourself already.
2- No 2 hammers. That does not work.
