Miquella the Kind

Defender, Hexproof
Whenever a creature becomes blocked by Miquella
the Kind, prevent all damage that creature would
do. Put a Love counter on that creature. Creatures
with Love counters cannot attack you or use their
activated or triggered abilities to target you or
permanents you control.

"Miquella the Kind is a monster. Pure and radiant,
he wields love to shrive clean the hearts of men. There
is nothing more terrifying."
