Catch-up ramp dressed in a cat's body. The trigger reads the table before it acts: it counts the players who control more lands than you and finds that many Plains, so it scales to how many opponents are ahead rather than how far ahead they are. That makes it a self-correcting fixer rather than a flat ramp piece, dead when you are leading and most generous when everyone else has outpaced you. The cards go to hand, not the battlefield, so this is card advantage and color smoothing rather than acceleration; it refills a curve you missed instead of skipping ahead of it. The design lineage runs through parasymmetrical land effects like Land Tax, which similarly reward falling behind on permanents, except this trigger reads the whole multiplayer board rather than a single opponent's land count. The clause that shapes it is the Plains restriction, and that restriction is sneakier than it looks: it finds any card with the Plains type, which means Plains-typed duals and triomes come along with the basics. That is precisely what lets the effect serve a multicolor white deck rather than punishing one, turning a fistful of fetched lands into fixing for a second or third color instead of a stack of identical basics. The 2/2 attached to the trigger is incidental, a body to chump or trade once the value has already been banked.
