In the most part Yes. See above.
Did you look at that table I made there?
Cards like this are the wrong way of designing CCG's. All cards should be equal in "power", only different. This card does what Towers do but almost 3 times faster. It's not only different, it's clearly a much better card.
Forget all the math and mechanics. I just want to address this point here.
Let me think of a good way to say this...oh, I know.
Let's pick two creature cards, Otyugh and Fate Egg. Now tell me which one you'd rather have if they could both be immortal under the old rules.
If you're indecisive, let me break it down for you. One of these cards can win the game by itself. The other may amuse you for less than 15 seconds.
Equal in power? Not even close. But obviously Elements isn't badly designed, or you wouldn't be here.
Now, I suppose you could argue that Otyugh can't win every game. Entirely true. But this card can't shine every game either. In fact, most of the cards in Elements are like that: they can be ludicrously good or abysmally bad depending on the situation.
And Heal is under-powered .
Anyway, I'm in the OP camp on this one.
For any and every mono deck where I use nine or more towers, I would replace six with six of these. Simply for the reason SG stated.
In fact, if I could, I would replace EVERY tower in a mono deck with these. Or reduce the number of quanta-generating things. So you discard your first turn, if need be. Let's look at that scenario.
1 Tower vs. 1 SoP.
Tower turn 1: 2
Tower turn 2: 3
Tower turn 3: 4
SoP turn 1: 0
SoP turn 2: 2
SoP turn 3: 5
Even without drawing a single tower on turn one, as long as you're mono deck with the same mark, you get more quanta by turn 3. That's just plain faster. It would be *almost* like taking all the cards in your deck and dividing their cost by 3.
Congrats, you've got yourself one more quanta by turn 3.
Everyone's also assuming this card has some kind of godlike staying power. In a world where Steal and Deflag exist, there's no guarantee that this card will even be on the field at that time.
Kael also brings up a point: the auto-mulligan system also will make sure you never open with too many of these.
I'm not going to look into how that system works as I'm tired, but I think if you run it through a hyper-geometric probability calculator, you'll find that Pups hypothetical situation rarely happens.
