Inspired by the same discussion as "outflank". What's the opposite of many "non-land" spells? This is. On the one hand, it doesn't have an immediate effect on the board. On the other hand, it sets your opponent back a whole turn, which could be devestating in a tempo race.

(I'm not sure what the rarity should be?)

I also considered putting the land on top of the deck, which would set your opponent back a whole turn in many respects (unless they want to play lots of cheap creatures, in which case it doesn't matter so much).

I wasn't sure about color. I considered white as white's more scour-y, and probably wants to get the weird bounce so blue can have the mainstream stuff. And neither has much land destruction. But bounce is usually blue.

Oof. That's harsh. I'd definately suggest against putting it on top of your opponent's deck, since then it would be a 1 for 1 trade and tempo advantage. As it is, you've already got that in 50% of the games where you play this card, since the opponent will often have 8 cards in hand and have to discard a card.

I'm pretty sure (though, I can't be certain) that if this card was printed, it would appear in 100% of the tier 1 decks playing blue. Card advantage be damned... that much tempo advantage is crazy strong. Imagine a player with this hand:

Island
Island
Windscour
Windscour
­Cancel
­Cancel
­Think Twice

If you had no one drops, that player would roughly have you over a barrel. He'd bounce your land two turns in a row, then be ready with the counterspells if you played a card, or Think Twice to replenish his hand if you didn't. Good Game.

Reminds me of the YUMD decks (Yucky Blue Mana Denial), using Hoodwink and Boomerang to achieve just that.

Could one print this? Yes. Should one? No way.
