More Special Energy Questions

[Dek]

Well, since my Magma/Aqua energy question was a flop (destroies about 5 strategies already), im back with another question.

Lets say I have an Expedition Tyranitar and i was going to use its attack, Stamp. I have a Darkness Energy and a Double Rainbow energy. Here's the facts that most of us know by now:

Darkness adds 10 damage
DRE subtracts 10 damage

So if both types of Special Energies are attached to my darkness pokemon, would the special effects of each energy cancel each other out (in other words, would my darkness pokemon do normal damage)?

Tyranitar needs 4 Energy for the attack, but we'll keep going.

Darkness Energy is applied before Weakness & Resistance.
DRE is applied after Weakness & Resistance.

It doesn't do a *direct* cancel of effects - Darkness could hypothetically get doubled by Weakness.
