Mana Reduction

Cleric spells you cast cost less to cast. This effect reduces only the amount of colored mana you pay. (For example, if you cast a Cleric spell with mana cost , it costs to cast.)

: Exile target creature card from a graveyard. This creature becomes a copy of that card, except it has this ability.

Lands you control are Plains. Nonland permanents you control are white. The same is true for spells you control and nonland cards you own that aren't on the battlefield. You may spend white mana as though it were mana of any color. You may spend other mana only as though it were colorless mana.

You may have this creature enter as a copy of any creature on the battlefield.
