But Aetherspouts is a bit better. It's only one more mana, and it sends the creatures back to the deck. In fact, it even makes your opponent decide which creatures go on top and which creatures go on the bottom. So instead of simply giving your opponent creatures back to the hand, you deprive them of all those creatures, making them have to draw them again. Then they have to choose whether they want to draw those creatures again sooner or later. Ouch.
In Standard, this card gave Blue decks a nightmare for aggro decks to deal with in their arsenals. It did see some Standard sideboard play at the very least, as the perfect counter to ultra-aggressive decks. Five mana was just too much for Modern, though, and since rotating out of Standard hasn't been seen competitively. However, in Commander, it's become a staple in many Blue decks, so this card still definitely has a home.
