Monstrous Vortex
Enchantment
Whenever you cast a creature spell with power 5 or greater, discover X, where X is that spell's mana value. (Exile cards from the top of your library until you exile a nonland card with that mana value or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)

The mana value of a split card is determined by the combined mana cost of its two halves. If discover allows you to cast a split card, you may cast either half (as long as its mana value is less than or equal to the effect's discover value) but not both halves.

If the discovered card has X generic mana in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

When you discover, you must exile cards. The only optional part of the ability is whether you cast the exiled card or put it into your hand.
