Anndrassil, Nature's Wrath

If a player would lose unspent mana, that mana
would instead be added as colorless mana at the
beginning of your next precombat main phase.
Natural Order - Players cant draw more than
3 cards every turn, and creature cards in
graveyards can't enter the battlefield.
''So it shall rise, as Mother Nature cries, to reclaim
what was lost, the invaders shall meet their demise.''
—Setassan Druid
