supernova burns a card , this one is free...
so if i suggest a photon that is a 1/1 creature and 0 cost that makes you draw a card you have to make a dominating deck with this card to prove that it's poorly designed?
No, because you are getting a windfall of a 1|1 creature. You are getting 2 cards for the cost of one card.
There is no windfall in the Quantum Flash. You don't get anything more than what you paid. Just a reorganisation of what you already have and in the sense that you do gain organisation you lose control of what quanta the flash picks up to convert, so you can only guarantee the 3 quanta that you are changing over and nothing more. You accuse of a badly designed card but show no Maths, no Statistics and no evidence of play that hasn't already been considered.
quantum tower + this card = 3 mana of a single type on turn 1
Lines like this mean nothing, I could get 3 towers of my element on the first turn and have 3 quanta on turn 1. In fact its more likely than your example because I can have an open tower count whereas you can only have a limited 6 flashes of the type needed to cast the Particular card you want. Now if you flood your deck with multiple flash types you could with 1 Quanta tower skip to nearly any card in your deck, but then again with a reduced deck of key cards, what are you going to deploy that is suddenly going to be able to give you the win?
If you want to dispute me, prove it, not just whine.
