New Frontiers
Green rarely gives ramp away, and the entire design tension of this card lives in the fact that it does. Every player gets to dig the same pile of basics out of their deck and drop them onto the battlefield, so the acceleration is shared down to the last land. The exploit is not who searches but who is built to spend the new mana first: a fast green deck wants those lands the turn after they arrive and does not care that the control player across the table got them too, because that player rarely needs the gas the same way. The lands come in tapped, which delays the payoff to the following turn rather than enabling a same-turn detonation. The search is optional for everyone, but that optionality is a soft offer rather than a real choice; even a player flooded on lands gains by thinning basics out of future draws, so the symmetry is almost never refused. The X cost is what makes the gap matter late: rather than topping out at a fixed handful of lands, the effect scales with whatever mana the caster can dump into it, and the asymmetry grows with the size of the dig. Group-ramp effects are a thin lineage, and most that share this shape pay for their generosity exactly here, by trusting the caster to convert a public resource before anyone else can.
