I was dinkin around at the work table and came up with these as a way to track pain tokens for Dark Eldar units.
On first pain token, place the counter.
On second token place on of the heads on the stack.
On third, place the third head onto the stack.
So far I have one of Chaos Marines, one Eldar, and one Tau.
They still need paint but I think it should be an easy way to track who did what to who for how many cookies.
