Fairy in a Bottle

Permanents you control gain hexproof
and indestructible until end of turn.
"Fairies can be found in Pink Fairy Fountains,
in Gossip Stones and in pots in dungeons, among
other places. Pink Fairies can be caught in a
bottle or absorbed to fully heal your hearts.
A Fairy caught in a bottle will fully heal you
automatically even if you fall in battle."
