Basalt Golem

Destroy target creature. It can't be regenerated. Its controller creates a 1/1 white Spirit creature token with flying.

Untap target nonattacking creature. It gets +1/+3 until end of turn.

When this creature dies, you gain 3 life. Whenever a player casts a white spell, you may pay 1. If you do, you gain 1 life.

If a spell would deal damage to a permanent or player, it deals that much damage minus 1 to that permanent or player instead.

Tap all nonwhite creatures.

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.

G, T: Target creature gets +0/+1 until end of turn. U, T: Put target creature you control on top of its owner's library.

Cast this spell only during the declare blockers step. Target unblocked attacking creature becomes blocked. (This spell works on creatures that can't be blocked.) Draw a card at the beginning of the next turn's upkeep.
