Snapcaster Mage's Flashback Ability and Phyrexian Mana

[LotusHead]

Can Phyrexian cost be used to pay flashback for spells given flashback by Snapcaster Mage?

I know Trinisphere does not care if you pay 2 life to replace that mana. It just wants 3 Mana (so phyrexian mana does not get around Trinisphere, but you can pay the 2 life if you want).

Thanks in advance.

Yes.  Snapcaster Mage gives the chosen card a flashback cost equal to its mana cost.  If that mana cost includes Phyrexian mana, then the cost may be paid as usual.
