Slipstream Looter

Sinuous Benthisaur is a tabletop tool for decks that prize setup and card selection. The creature arrives as a 4 4 for a heavy cost and immediate value. When Sinuous Benthisaur enters the battlefield you look at the top X cards of your library where X is the number of Caves you control plus the number of Cave cards in your graveyard. You choose two to take into hand and send the rest to the bottom of your library in a random order so you get targeted digging without reshaping your whole deck.

Use this in midrange blue shells that can reliably produce the required mana and maintain Caves on the battlefield. The interaction favors a patient plan, pulling specific answers or threats while leaving less useful cards out of sight. It pairs cleanly with sacrifice outlets and graveyard recursion since those increase X and improve the selection quality. Sinuous Benthisaur fits best where precision matters more than tempo.
