Living Tsunami
A 4/4 flyer for four mana is two points over the rate blue usually pays for evasion, and the upkeep tax is how the design buys that body down: every turn you keep it, you return a land you control to your hand or lose the creature. That recurring bounce is not a one-time cost like Man-o'-War's enters-the-battlefield trigger; it compounds, costing you a land drop per turn just to keep a 4/4 on the table. The clever wrinkle is what you choose to return. Point it at a basic and you simply replay the land, paying in tempo rather than resources. Point it at a land whose own enters-the-battlefield trigger you want again (a scry land, a value land, a creature-land that wants to redeploy untapped) and the maintenance penalty turns into a repeatable enabler, firing the same effect each upkeep instead of bleeding you. That inversion (a drawback you can aim at exactly the land that profits from being replayed) is the strategic axis the card lives on, and it is why it reads as fragile filler in one shell and a deliberate engine in another. The Elemental flavor of a tsunami that recedes only to gather itself again is unusually well matched to the mechanic: the creature literally pulls land back into the sea each turn, and you sacrifice the body the moment you cannot. This is a creature whose drawback is the entire pitch, and the better the land you feed to the bounce, the more the math tilts your way.
