Launga, Ookii Priest

When you cast Launga look at the top 8 cards of
your library. Reveal any number of these. For
each card revealed lose 1 life and put that card in
your hand. Shuffle the rest into your library.
If an opponent was dealt damage on your last
turn by you or a creature you control, if you or a creature you control would deal damage to that
same opponent this turn double that damage.
"Fate is mine."
