i play in a meta where 1) very predictable opponents colorwise (and they dont play blue!) 2) they almost exclusively use basics 3) mostly 2HG 4) they never slot in enough enchantment removal.
My understanding is i can name
Plains. which will have the guy playing white (assumed) either split his mana going forward (dropping a land while the rest are phased) or essentially skipping every other turn. are you saying i cannot name
Plains?
Ruling i found in Scryfall.com says: Can affect basic or non-basic types, but it must be for a specific type. The chosen type must be an existing land type. See the glossary of the comprehensive rulebook for more details on existing land types.
