Flying Haughty Djinn's power is equal to the number of instant and sorcery cards in your graveyard. Instant and sorcery spells you cast cost {1} less to cast.

Mercurial Spelldancer can't be blocked. Whenever you cast a noncreature spell, put an oil counter on Mercurial Spelldancer. Whenever Mercurial Spelldancer deals combat damage to a player, you may remove two oil counters from it. If you do, when you cast your next instant or sorcery spell this turn, copy that spell. You may choose new targets for the copy.

Surveil 1. (Look at the top card of your library. You may put it into your graveyard.) Draw a card.

Look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in any order. Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

Return target creature to its owner's hand. If its mana value was 3 or less, scry 1. (Look at the top card of your library. You may put that card on the bottom of your library.)

Casualty 1 (As you cast this spell, you may sacrifice a creature with power 1 or greater. When you do, copy this spell and you may choose a new target for the copy.) Counter target spell unless its controller pays {2}.

Surveil 3. (Look at the top three cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.) Flashback {1}{U} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Put a +1/+1 counter on target creature. It phases out. (Treat it and anything attached to it as though they don't exist until its controller's next turn.)
