Ghost Warden is cool with me, but this would be intended to be a mechanic on multiple cards, so it'd be a red-flag any time it popped up at common.
A flat +1/+1 would be the simplest method I think. I think for a moment I did consider Joint N, but it wouldn't have necessarily gone of the creature's p/t.
Akrasan Squire isn't strictly worse in that you could attack with the squire and it gets its own bonus. That's pretty good. Can't block with the Squire to get its own bonus, though. Attacking is better than blocking, but this is more generally useful, so I'd say this is better than Squire, which is quite a good card to begin with.
Which is not to say that this card isn't possible. Wizards bumps the power level in creatures all the time. Though I would give 0/1 some consideration.
: Target creature gets +1/+1 until end of turn.)
Not nwo compliant unfortunately.
Ghost Warden? Well, red-flagged under NWO is not impossible. But I generally wouldn't want too much of it.
Does this always add +1/+1 ore does it depend on the base p/t?

As an aside: Better than most cards that do something similar. Ghost Warden was mentioned. Infantry Veteran/Anointer of Champions is strictly worse (unless you need a Kor, or an Advisor?)
