Ive had both of these pieces for a bit now and haven't even used them. What would be the best way to utilize them in 300pt modern with resources?

I have the Green, Blue, and Yellow batteries all with the 6 usual constructs.

I also have the book of the skull with Kuurths, Grieithoths, Skirns, and Mokks hammer.

I'd say possess with ion, green pb (get a sniper rifle) fill in with to support that can be carried to break the pact.

I played this team a couple of weeks ago:

The Flash (KC) 195
Turtle 50
ION 25 (I played Ophidian instead for sidestep/pulse wave)
Green Power Battery + Green Power Ring (10)
Axe 6
Decoy 6
Shield/Net/Stop Sign 8

I played an 8 points construct or 6 points construct to keep pushing the battery with colossal stamina in the special power no. 3

Went 1 - 1 (only two rounds), lose the first because I was playing against a BoS team, so, the time I took to push the battery to clicks 19 - 20 was enought for the other team to equip all 7 hammers on their figures...
