Aether Adeptutility$0.12This is the cleanest modern analogue to Man-o'-War, providing the same 2/2 body plus an enters-the-battlefield bounce effect for a creature. It fits the same blue tempo role and mana cost slot.Reflector Mageutility$6.65A stronger tempo version that bounces an opposing creature and prevents it from being recast next turn. It plays the same disruptive creature-bounce role, though it costs one more mana and requires white.Lorescale Coatlutility$0.16Like Man-o'-War, it can be used in blue tempo shells with creature interactions, though it does not bounce on entry. If you want a budget-ish blue creature that supports similar board-pacing plans, this is less direct but still in-color utility.Aether TradewindsutilityBudget$0.04This instant can return a creature you control and a creature you don't control, often functioning as a bounce spell while also reusing your own enters-the-battlefield creatures. It is a close tempo/combo tool for blue bounce decks.Unsummonremoval$0.16A direct budget alternative for the bounce portion of Man-o'-War, trading away the creature body for cheaper instant-speed interaction. It fills the same tempo/removal niche in blue.Into the Roilremoval$0.17This is a flexible blue bounce spell that can hit any nonland permanent and optionally replace itself. It is broader than Man-o'-War but serves a similar tempo disruption role.Venser, Shaper Savantutility$0.72This is a classic blue bounce creature that can return any spell or permanent to hand, often acting as a flash-speed tempo swing. It overlaps strongly with Man-o'-War's interactive creature-bounce game plan.Shrieking Drakeutility$0.21A very similar cheap blue bounce creature that returns a creature you control to your hand on entry, enabling repeated ETB loops. It is more combo-focused than Man-o'-War but plays in the same blue creature-bounce space.
