Margit, The Fell Omen

Ward - Discard a Card.

At the beginning of each upkeep, create a colourless equipment artifact token named “Spirit Weapon”
with Equip {0}, “Equipped creature gets +1/+0”, and
"{t}, Sacrifice this card: Deal 1 Damage to any
target”.

If Margit would die, exile it instead and return it to
the battlefield transformed under its owner's control.
