***, Who Damned Himself

Whenever you cast an Avatar, Eldrazi, or Kraken
creature spell, draw a card. If 7 or more mana
was spent to cast that spell, each player exiles the
top card of their library. Until the end of your
turn, you may play lands and cast spells from
among cards exiled this way without paying their
mana cost. Then, if that spell is legendary and 10
or more mana was spent to cast that spell, copy
spells you cast from exile until the end of turn.
(A copy of a permanent spell becomes a token.)
