This is most useful on light/fire dragons so I'll approach it from there.
Unupped, on crimson dragons, this is four quanta for one card. Immolation is seven for two cards, gives one of each other quanta, and requires no quanta to start up. The possibility of using it on golden dragon improves it some. I'd say a little UP.
6x immo
6x photon
6x this
6x gold/crim dragon
6x precog/other cheap card and mark to match
Upped, it's nine quanta for one card and a quarter of your health. Cremation is nine for two, so this is ~a card for 25 health. That seems about fair. Again, light dragon may improve this a bit.
6x cremation
6x rol
6x light dragon
