Much like similar cards, he should have Vigilance and Convoke and the text should be Other creatures.

The goblin lord in m11 has haste in addition to his granting ability because they don't want him to grant himself +1/+1. Wizards has done lords or lord type effects that include the card themselves in the effect. On this card it's infinitely cleaner, and having vigilance is important to enabling the convoke action.

Actually the Goblin lord in M11 has haste because he's supposed to have haste even if he somehow stops being a Goblin or if his ability stops referencing Goblins. This guy, however, will always get Vigilance from himself unless he stops being a creature, in which case it wouldn't matter anyway. Also, as is he doesn't have Convoke.

Maybe a touch too aggressively costed since once its done its so good at speeding up creature drops without slowing swings?

On the flip side, anything abusing the convoke/vigilance combo will probably run out of cards pretty fast, and be vulnerable to wraths.

I think it looks more powerful than it is, but I'll try building a weenie deck powered by card draw to see if it's a bit too much of an engine.

@Latronis: Nah. White gets very good 2/2s for : look at Kazandu Blademaster, Leonin Relic-Warder, Knight of the Pale Orchid and many other knights. This is an awesome card, but not excessively strong.

There's still such a thing as too good, I feel the combination of giving your down critters vigilence and hand critters convoke potentially too good a creature acceleration (without overly impacting ability to swing and all on one card) on a 2\2 for 2.

Potentially; I'll wait to hear what the next level of testing brings out about it.
