Jegantha

Jegantha, the Wellspring is a legendary elemental elk from the plane of Ikoria.

Jegantha is mana incarnate. This monster seems to amplify every and any magic cast in its vicinity. The planeswalker Vivien Reid tried a simple enlarging spell on a beetle, which assumed truly colossal dimensions. Vivien wonders what could Jegantha do if it should have a bonder.
