Consuming Tide
There are only a few cards that can be compared to Cyclonic Rift, a commander staple. But here is another contender from Innistrad Crimson Vow. It's only a sorcery and not an instant, but it needs only four mana, while most other similar cards are much more expensive.
Consuming Tide won't break the format or anything like that, and many players will find sorcery speed ineffective, but in certain decks that run Jhoira, Weatherlight Captain this could be an excellent additional effect for playing your free mana rocks to draw more cards.
