Painted Pebbles

{1}, {t}: Add {c} to your mana pool.

Whenever you would cast your second colorless spell this turn, Painted Pebbles becomes a 1/1 artifact creature until end of turn. It is an Elemental in addition to its other types, and it gains haste and indestructible.

It's much more than an artform or a plaything. Giving the divine offering of a host to the spirits is a rite of passage for those seeking the eternities.
