Counter target spell. Create X 1/1 colorless Thopter artifact creature tokens with flying, where X is that spell's mana value.

Return six target nonland permanents to their owners' hands.

Exile the top eight cards of your library. You may put a land card from among them onto the battlefield. Until end of turn, for each nonland card type, you may cast a spell of that type from among the exiled cards without paying its mana cost.

Exile the top seven cards of your library. Until end of turn, you may cast spells from among them. If this spell was cast from your hand, add ten mana of any one color.

Target player takes an extra turn after this one. Shuffle Beacon of Tomorrows into its owner's library.

Search target opponent's library for a creature card and put that card onto the battlefield under your control. Then that player shuffles.

Cascade, cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom of your library in a random order. Then do it again.) Call Forth the Tempest deals damage to each creature your opponents control equal to the total mana value of other spells you've cast this turn.
