This is another "WOW! That's a common!?" for me. There's so much going on here. The effect is extremely narrow, so even with the damage AND the life-gain clauses, I think it can cost less. Look at Turn Aside and Hindering Light, for example.
This is an odd card. It's very expensive without its alternate cost, which then seems extremely cheap by comparison. Exiling graveyards is very cheap, of course, so half of that's okay, but proliferating can be very powerful. I'm also not sure proliferate (outside of its block, where it was stretched into all of the colors) belongs in this color combination. I suppose it makes sense in green and white as colors of growth... okay, I convinced myself a little bit. It just looks very odd at first glance.
I think it's not a good idea for any common to tap for two mana. That's too much acceleration - your six drops randomly land on turn 4, your seven- or eight-drops randomly land on turn 5. Palladium Myr was uncommon, as is anything else that reliably taps for 2 mana. There are commons that are oneoff versions (Generator Servant) or unreliable (Scorned Villager, the new Whisperer of the Wilds).
I also think it's going to be really confusing having a common that produces two mana, in two different colours, with a conditional rider, that does two different things, and can even apply to two different creature spells in one turn... That is one very, very complicated common.
Make this uncommon and all my objections go away, though. This becomes simply a rather cool card. (Albeit one in a really weird set of colours. I'd expect this to be green, maybe red. A white-black creature tapping for is exceedingly unusual. You could fix that bit if you made the mana only usable on spells of certain creature types.)
these are all tentative numbers and needs some tweaking.

Is this really supposed to be common? :O
