Steven, Crystal Gem

You may use mana as though it were mana
of any color to cast creature and planeswalker
spells.
At the begining of your upkeep, look at the
top card of your library. If it is a creature or
planeswalker spell, you may revel it and put
it into your hand.
{w}{u}{r}{g}: Creatures you control get +X/+X,
where X is the number of legendary
creatures and planeswlakers you control.
