Tui and La

At the beginning of your upkeep, draw a card
then discard a card.
As long as it isn't your turn, other Waterbenders
you control get +0/+3 and Reach.
Sacrifice a Waterbender you control: return Tui
and La from your graveyard to the battlefield.
Activate this ability only any time you may play
a Sorcery.
