FoC + RoI + Constructs

[dense flame]

I know it's not a construct but Null seeker might still be worth it to smooth out gem requirements?

Null seeker is a bit slow, but worth a try. Originally I had 50 cards total, but reduced it to 40.

it's not worth it. agitator is generally better - doesn't need to survive until the next turn, doesn't need to spend mana, doesn't sac itself, and still covers 3/5 possible gem colors you'd need to burn at that point

null seeker's advantages would be acting as a 2/3 body, and maybe being able to pre-burn annulus fabricator

but on balance, I don't think that's worth it

also, you can use agitator as a 3 mana card that creates 2 minions
