Giants you control have reach and trample.
Giant spells you cast cost {w}{r}{g} less to cast.
This effect reduces only the amount of coloured
mana you pay. (For example, if you cast a Giant
spell with mana cost {4}{g}, it costs {4} to cast.)
Whenever a Giant you control dies, it deals
damage equal to its toughness to a non-flying,
non-Giant creature chosen at random.
