Painter\'s Penance

Put a card from your hand on top of your library: The next time a black or red source of your choice would deal damage this turn, prevent that damage.

At the beginning of your upkeep, if an opponent controls more lands than you, you may search your library for up to three basic land cards, reveal them, put them into your hand, then shuffle.

As this creature enters, choose a color. All cards that aren't on the battlefield, spells, and permanents are the chosen color in addition to their other colors.
