Peak Existence

The "legend rule" doesn't apply.
You have no maximum hand size
Choose one-
{7}{g/w}{g/u}{b/g}{r/g}{t}:Each nonland permanent you control is all colors.
{8}{g/w}{g/u}{b/g}{r/g}{t}:Lands you control are every basic land type in addition to their other types.
{9}{g/w}{g/u}{b/g}{r/g}{t}:You can't lose the game and
your opponents can't win the game.
{10}{g/w}{g/u}{b/g}{r/g}{t}: Spells you cast have no mana cost.
