Frederic, of the Ineffable

If casting an Eldrazi, Horror, Nightmare, or
Kraken creature spell would cause an ability of a
spell or permanent you control to trigger, that
ability triggers an additional time.
Whenever you cast an Eldrazi, Horror,
Nightmare, or Kraken creature spell, draw a
card. Then, if that spell is mana value 5 or
greater, each opponent exiles a card from their
hand. You may play cards exiled this way.
