Lakshmi, The Abundant One

As long as Lakshmi, The Abundant One is on
the battlefield you have no maximum hand size,
and whenever you draw a card, add 1 mana of
any color to your mana pool. Until end of turn,
you don't lose this mana as steps & phases end.
{3}: Draw a card.
"Who can possibly fail when all of eternity is
on their side?"
