So hyperdrive and then play something like fractal kills you? Since hyperdrive would make you lose all your life when fractal trys to take it all? XD
Technically I would say the "consumes all quanta" on those spells is part of the EFFECT of that spell rather than the COST and therefore it should not automatically kill you like that(though to keep this card at all balanced in combination with fractal or miracle, something like this would have to be done anyway).
Even with this restriction though, I would argue that allowing any quanta to be used to pay the cost of this card makes it very OP. Consider an opening hand of 4 quantum towers, hyperdrive, 2 elite phase dragons. On turn 1, before your opponent has any chance to react, you now have dealt 20 damage to him and have 2 untargetable 10/6 creatures in play. It cost 28 of your own life to do this but since he can't do anything about your dragons, they will easily make up for that on the next turn and even without playing anything else after that, you have a 5 turn kill. Ruby dragons would be even more damage at a lower life cost but at least could be killed the next turn.
