I'm most worried for the Voodoo + Momentum combo with this. If swapping HP for attack is considered damaging, then we have a potential broken combo.
Again with the openEtG references (because hey, they tested a lot of new concepts in there), there is a card called Equalizer. It sets the HP of the creature in the value of its attack (like this card, but not changing the attack).
There was a pretty powerful and probably broken 200 damage OTK that was: Voodoo + 4x Basilisk Blood x Momentum + Equalizer + Parallel Universe. The equalizer sets the HP of the doll (101) into attack (1), dealing 100 damage. The thing that made it so hardcore was the extremely low quanta requisites (3 Supernovas).
The combo was nerfed by setting the max HP of the creature on the balue of the attack, so the PU won't duplicate the damage. Yet, I modified the combo for a (still broken) Voodoo + Momentum + 4x BB + PU + 2x Equalizer. Now, what makes it so powerful if it requires so many cards?
- Voodoo is a virtually unkillable creature with CC, besides Rewind which almost no one uses.
- The combo is independant of the Singularities, so you can play multiple SNs in the last turn
- Playing early cards of the combo (voodo, Momentum and BBs) makes your hand less clogged so you can still drawing cards and playing SoBr
Let's have other people analize it, but this are my thoughts.
