Castle of Khaidves

(Palaces are treated as lands. You may play a palace
in place of a land on your turn. The number at the
bottom right corner indicates the number of Palaces
with the same name you can have in your deck.)
Whenever a Khaidve enters the battlefield, add
one mana of that Khaidive's colors.
{t}: Create a 1/1 Khaidive creature token that's all colors.
Sacrifice a Khaidive: You gain life equal to the
number of colors it has. Activate this
ability only once per turn.
