Prayer of the Faey

Whenever an other creature you control dies of
combat damage, Prayer of the Faey gains indestructible until end of turn.

Whenever Prayer of the Faey is dealt damage, you
may choose to double the number of damage dealt.
If you do, search in your library for a enchantment
card, reveal it, put it into your hand, then shuffle.

If Prayer of the Faey is put in your graveyard, add {u}{u}{u} to your mana pool.
