Instead of paying the casting cost for a spell of any color, its caster may choose and discard a card that shares at least one color with that spell. If the spell has o
X in its casting cost, X is 0.

This only replaces the mana cost (the mana in the upper right hand corner of the card). It will not pay additional costs from the card text (such as Buyback) or from other effects. It does not prevent you from paying those additional costs if you want or need to.
