Llanowar Elvesramp$2.29A classic one-mana mana dork that accelerates early development by tapping for mana every turn. It fills the same utility ramp role, though it produces colored mana rather than colorless or blue.
Fellwar Stoneramp$1.91A cheap utility mana rock that helps fix mana in many two-plus-color tables. Like Sea Scryer, it provides early mana acceleration for blue decks, though without the creature body.
Mind Stoneramp$0.31A two-mana artifact that ramps immediately and can later cash in for a card. It serves a similar early-game mana acceleration role with added late-game value.
Prismatic Lensramp$0.38A low-cost mana rock that can filter into colored mana after entering the battlefield. It is close in function to Sea Scryer’s colorless-to-blue mana conversion.
Mana Leakutility$0.45This is not a mana source, but it is a staple cheap blue utility card often found in the same deck shells as low-cost tempo creatures. Included as a blue role-adjacent option for early-game control plans.
Sky Diamondramp$0.19A two-mana artifact that enters tapped but produces blue mana reliably. It is a straightforward budget alternative for blue acceleration in the same cost bracket.
Coldsteel Heartramp$0.99A two-mana mana rock that fixes for any chosen color on entry, including blue. It plays a similar role as a cheap source of mana development for blue decks.
Thought Vesselramp$1.92A two-mana mana rock that taps for colorless and also removes maximum hand size. It mirrors Sea Scryer’s cheap utility acceleration, though it lacks blue filtering.
