Why is this card good?
Treasure Cruise is one of the most efficient card draw spells in blue, full stop. Drawing three cards for as little as when you delve away seven cards is absurd value, and it routinely casts for two or three mana in the mid-to-late game. Card advantage wins games of Commander, and few spells offer it this cheaply.
It shines in decks that fill the graveyard naturally: spellslinger/storm builds running fetches, cantrips, and instants/sorceries, plus self-mill and any deck with a deep graveyard. Commanders like Kess, Niv-Mizzet, or any blue control shell happily run it. The key constraint is having delve fodder — your yard needs to be stocked for Cruise to be cheap.
Don't play it if your graveyard stays empty, or if you lean heavily on graveyard recursion/reanimation, where exiling cards to delve creates real tension (Cruise competes with Murktide, Tarmogoyf-style payoffs, and flashback/escape costs). In those decks the "free" card draw isn't actually free.
Otherwise, near-auto-include in graveyard-friendly blue.
