Yavimaya Granger
The land-fetch happens the instant this hits the battlefield: a basic comes in tapped, your colors get smoother, and a card thins out of your deck. That entry value is unconditional and permanent, which is exactly what makes the echo cost so honest a piece of design. You pay once to deploy, collect the ramp, and then face a second on your next upkeep that buys nothing except a 2/2 you have already wrung dry. The decision the card forces is whether that body is worth a full second casting, and the common answer is no: let it die, keep the land, move on. Yavimaya Granger stands as one of the cleaner statements of what echo was meant to do in its era, deferring the real price to a future turn where the value has already been banked. The template (search a basic on entry, hand back a disposable body) became a fixture of green's ramp suite and outlived the tax that originally balanced it; later designs like Wood Elves and Farhaven Elf simply gave you the creature for free. This one charges twice and trusts you to know which payment to skip.

(At the beginning of your upkeep, if this came under your control since the beginning of your last upkeep, sacrifice it unless you pay its echo cost.)
When this creature enters, you may search your library for a basic land card, put that card onto the battlefield tapped, then shuffle.
