If you look at fixed mana costs, there are indeed better cards than Untamed Might. But this card is just so flexible! If you have nothing else to do, than cast a card to pump your creature,why use a card with lower mana cost and a weaker effect, when you have nothing to lose when going all out and pump it for more? While cards with fixed mana costs leave you calculating how you can precisely use the lands you have, this card can just be adjusted so that it fits in with your scheme.

Some people here seem to be missing the point. Paying four mana simply to get a +3+3 bonus which could easily be granted is not what this card is for. I would never, never use this card as a giant growth. Never. See below:
"For Untamed Might to give your creature +10/+10, you have to pay 11 mana. For Primal Bellow to give your creature +10/+10, all you need is to have 10 forests. You don't even need to spend the mana."
--Kelrath
This is assuming that you are running a mono green deck. You won't always have 10 forests in play, often you will have other lands that generate green mana, cards like overgrowth, etc. If you were using a mono green deck this would be much less effective than primal bellow. I run 2 of these in a {g}{u}{w} landfall deck, with high effectiveness. I can easily get a +12+12 bonus with this on the 5th turn. By then a windrider eel or something similar is in play and I'm swingi... (see all)

@Kelrath: Because not every deck plays strictly basic forests, not every deck is mono-green, and not every mana source is a land. If I wanted an effect like this in an Elfball deck (for example), since not all of my lands are forests and the bulk of my mana comes from tapping creatures, then I would definitely want this over Primal Bellow.

Since the designers wanted poison and non-poison damage to be at similar power levels in limited play, they made this the set's green pump spell, not some one-drop with a fixed effect (Can you imagine a limited poison deck with 3-4 Giant Growth or Prey's Vengeance in it?). I'm not a very good tourney player yet, but I had to laugh when I played it on a Plague Stinger with 
=7. Since I was attacking with two stingers, I sent my opponent straight from one to ten poison counters in a single flap of a thrummingbird's wings. :)

There is no card that has won more games in Som Draft than Untamed Might. Period.

wow some of you people need imaginations. Remember its green. Mana ramp? And its only one card. So for a +10/+10 bonus, you need this one card, or 3 vines of vastwood, or 4 giant growths. Use it mid-late game. Vines of Vastwood is better early game. This deserves full 5/5.
