So not only does it not work but this whole discussion is besides the fact that putting any kind of enchantment on such a low level, low health creature is almost always a bad idea. Level 1's are easily outclassed, and by investing more mana (and actions) into them you're 1-2 attacks away from losing your investment.
I don't think it would be a good idea even if BG's got the bonus...
Don't get me wrong though, post the release of acid ball low level creatures are great. Blue gremlins are very efficiently costed and generically strong for the mana, but that doesn't mean you should risk mana on their frail body.
Blue Gremlin has very high survivability for its mana cost. Adding Bear Strenght (or Lion's Savagery if it worked) make him a very hard hitter, with lots of survivability and mobility. They are my favorite level 2 creature.
I agree, but it doesn't change the fact that buffing out a low level creature with enchantments is a bad idea for a multitude of reasons, not the least of which is that it can be 1-2 shotted. Any control that goes off of level is then so much better against it as well.
Orc butchers also have high survivability for their mana cost, but the only enchant I'd be willing to put on them is the Standard, and that's only because it buffs other creatures.
