Sure, because something that pumps infectors instantly for a zero mana cost won't ever become broken.

Just had the ideal game: turn one Forest, Glistener Elf, turn two Mutagenic Growth, Mutagenic Growth, Assault Strobe, swing for lethal. Phyrexian mana changes things in a huge way. You're never really "tapped out".

Yes, I would like some Giant Growth in every deck ever, thanks for asking!

It doesn't take much for a turn-two win to happen with this card. In fact, this card makes my infect deck have a consistent turn 2-4 win. Best case scenarios usually play out like this:
Turn 1: Forest, Glistener Elf
Turn 2: Swamp, Groundswell, Mutagenic Growth, Mutagenic Growth, Tainted Strike
It's happened often enough to say that it's more than luck, but it doesn't happen often enough to say "Yeah, this deck consistently wins in two turns." If no Glistener Elf, even Llanowar Elves will do the job, or even a Birds of Paradise if you really need to. An Ichorclaw or Plague Myr will probably do the job too, just a turn late, though. Regardless, a Mutagenic Growth can be an invaluable card, especially with its low and potentially even lower mana cost.

With m13, Rancor is here. I'd love to see this happen:
Turn 1:
Forrest, Glistener Elf
Turn 2:
Moutain, Rancor. Assault Strobe, Mutagenic Growth, Mutagenic Growth.

@guitargamer79 - "Turn 2: Mountain, Mutagenic Growth, Mutagenic Growth, Assault Strobe, Assault Strobe,
ATTACK phase........Game Over."
That doesn't work. Multiple instances of double strike on the same creature don't stack; they're redundant. There's no such thing as "doublest" or "double double strike" because there are only two combat damage steps, the first strike step and the normal combat damage step. No matter how many instances of double strike a creature may have, it will only hit twice at most.

So it's now possible in theory to swing for 10 infect on turn two.
All you need is a Glistener Elf with two of these and a couple Giant Growths.
You'd need a lucky hand, but not that lucky. Just the idea that you can get to 10 poison on turn 2 without any especially devious combos is slightly disturbing. And awesome.

Free pump on lifelink creatures?
The more I think of it the more I love and hate the idea of 
mana. If ever there was a time for the players to stumble on crazy stuff that R&D had overlooked, this would be it. Being able to ignore color requirements by paying life is something I never thought I would see.
This, Mental misstep, phyrexian metamorph, porcelain legionnaire, surgical extraction... it makes me happy, and kind of scares me a little at the same time.
