Narada Muni

Indestructible
When a creature an opponent controls deals
damage to you or a planeswalker you control, you
may pay mana equal to the amount of damage it
dealt. If you do, that creature loses all its abilities
& becomes a 0/1 Red Arjuna Tree creature.
"He carries a song that could bring the Devas &
Asuras together."
-Valmiki
