Is there any reason to use basic lands instead of basic snow-covered lands?
There are plenty of cards that hose snow lands, in addition to the cards that @tehfurbolg posted.

Avalanche is MLD that only targets snow lands.
Cold Snap deals damage to each player during their upkeep equal to the number of snow lands they control.
Freyalise&#39;s Radiance prevents snow permanents from untapping.
Icequake and Thermokarst are land destruction that has an additional effect if the targeted land is a snow land.
Legions of Lim-Dûl and Rime Dryad have Snow Landwalk.
Rimefeather Owl has it's power and toughness equal to the number of snow permanents on the battlefield.
Ronom Hulk has protection from Snow, which probably doesn't do much with snow basics but if the land gets animated then they can't block Ronom Hulk.
The recntly spoiled &quot;Reidane, God of Justice&quot; // &quot;Reidane's Shield&quot; from Kaldheim has a static effect that causes snow lands your opponents control to enter the battlefield tapped
