The All Form

Changing
Creatures you control are every creature type.
The same is true for creature spells you control
and creature cards you own that aren't on the battlefield
{w}{u}{b}{r}{g}{t}: Look at the top six cards of your
library. You may put a creature card among them
into play with converted mana cost X or less,
where X is equal to the number of creatures you control. Put the rest on the bottom of your
library in any order.
