I came up with an alteration to the system.

Option 1 Roll the Power Dice & just use it as a Self-Contained pool (so if I had 3 PD & rolled a 3, 6, 7, my result would be 3x7).

Option 2 Don't roll PD at all, they are equal to the highest Dice you roll.

So I roll 5 dice & get a 9, 2x7, 4, 1 & I have 3 HD, I would have 4x9 or 2x7 as sets.

Conscider changing Hard Dice to Hyper Dice & Wobble Dice to Wild Dice.

Option 3 roll 1 Die for all HD & it is their value.
