Lillia, the Wandering Soul

Whenever you play a Swamp land card, create a
1/1 white Spirit creature token.

Whenever a spirit you control dies, you may pay
life equal to its power. If you do, create a Grief
token attached to another target creature you don't
control. (It's an Aura enchantment with "Enchant
creature" and "Enchanted creature doesn't untap
unless it's controler pays {1}.")
