Spirit of the Atog

Spirit of the Atog's power and toughness are
each equal to the number of colors of mana
spent to activate the ability of Atog Sanctuary.
As long as Spirit of the Atog is on the battlefield,
it has all activated abilities of all Atog creature
cards in your graveyard.
"Believe me, it's not a good idea."
—Hans, to Saffi
