Just giving Mogg Fanatic first strike would make it playable again, and it's not like that puts it out of the power range for today's standards.

I'd like to see a new engine card similar to Loam get printed. Something like:

Brainburst
1U
Sorcery
Draw two cards.
Discard a card: return Brainburst from your graveyard to your hand.

Something along the lines of that, I guess. It might have to be 2U to not be overpowered.
