The Gatewatch

You can't play The Gatewatch from your hand during your first turn of the game.
Ally spells you cast cost {w}{u}{b}{r}{g} less to cast. (You can't discount a mana symbol that's not in the casting cost of a spell.)
{w}{u}{b}{r}{g}, {t}: Put five 1/1 Ally creature tokens onto the battlefield, each one a different color. (The colors are white, blue, black, red, and green.)
