Search creatures with land-tutoring enters triggers form a long, branching family, and this is one of its leaner, more restrictive members: mono-white, locked to a single land type, and slow to pay off. The four-mana cost over a 2/2 buys thinning and a Plains drop wrapped around a body, with the tapped clause acting as the brake. Rampant Growth and its kin cost less and carry no creature; stapling the effect to a 2/2 means the land lands a turn behind where a dedicated ramp spell would put it. The Plains restriction is the other real cost: this is white doing the work white does worst, paying for the privilege with the narrowest possible search target. What you get in return is a creature on the board, which matters more in slots that want bodies than in any deck trying to ramp on rate. The same template also appears on Wood Elves, Solemn Simulacrum, and the broader family of value-on-a-stick ramp; this one sits near the bottom of that curve. Reliability is not the pitch, since a creature spell can be countered before its enters-the-battlefield trigger ever resolves, same as any ramp sorcery. The pitch is that when it does resolve, you keep both the 2/2 and the Plains, which a one-shot growth spell never offers.
