Iambi, Mystic of Lotus Falls

Hexproof
At the beginning of each upkeep, create a Mystic
Lotus token. (It's an artifact with "{t}, Sacrifice
this artifact: Add two mana of any colour to your
mana pool.")
The Lotus Falls give life to mystic spirits and flowers
of immense power. The spirits nurture these lotus blossoms, maintaining a balance of mana that
enhances life for all.
