msem-instigator

Wanderlust — When you cast this spell, you may copy it if you control four or more differently named lands.
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 a random order.

Choose target instant spell, sorcery spell, activated ability, or triggered ability. Create a Function token with its effects. Then you may pay {1}{U}. If you do, counter that spell or ability. (It's an enchantment. As you cast an instant or sorcery spell, sacrifice any number of Functions to add their effects to that spell. A spell's effects includes added functions.)

Return target nonland permanent to its owner's hand. Then you may pay {U}{U}. If you do, copy Resonating Force and you may choose new targets for the copy.

Enchant permanent
Whenever a counter is removed from enchanted permanent, you may put a counter of that type on another target permanent.

You may cast this spell as though it had flash if you pay an additional {2} to cast it.
You may have Resourceful Impersonator enter as a copy of any creature on the battlefield.

Target nonland permanent phases out. (Treat it and anything attached to it as though they don't exist until its controller's next turn.)
Draw a card.

You may draw four cards. If you do, skip your next turn.

Flashback {3}{U} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Counter target spell. Its controller draws a card.

Shuffle your graveyard into your library, then draw two cards.

Choose target spell. If it's an instant, a sorcery, or you cast this spell from exile, copy it. You may choose new targets for the copy.
Prophecy {2}{U}{U} (Once each turn, you may exile a card with prophecy as you reveal it. When you do, you may cast it for its prophecy cost as long as it's exiled.)

Your opponents play with their hands revealed.
I, II — Return target nonland permanent an opponent controls to its owner's hand.
III — Gain control of target nonland permanent.
