Chara, the First Fallen

Soulless (Chara is a legendary enchantment unless
you control a soul token.)
{4}{g}{u},{t}; Choose one: End target player's turn,
they may draw a card; or you create a soul token.
(It's an artifact soul token with "{t}: You gain one
mana of any color.")
As long as Chara is a legendary creature, creatures
you control have hexproof.
