It doesn't general appear on permanents below uncommon for that reason, and it's much less mana efficient than you seem to believe. See Azure Mage: it usually costs no less than 4 mana. I suspect you could get away with 3 or maybe even 2, since this must .
Yeah, I'm afraid this is a rare effect that costs twice as much and is half as big: Archivist. Dreamflux also needs to be rare, but might be able to just go up to costing 5.
If you want this to stay at common, it pretty much needs to gain "then discard a card". At uncommon, you could probably make it just ", : Draw a card".

This is still a 2/2 for two mana with an upside in blue. You know what the cost/body ratio for a looter usually is? Merfolk Looter.
