As an example, Emchompite says that cards that were included within Japanese sets, like the Secret Rare Yveltal EX from Best of XY, but as promos in English, are usually more expensive in Japanese just due to the nature of their release (i.e., having to pull the card from a pack vs a guaranteed promo card in a product)
For those who are not interested in spending $20+ on a single card, Oreskos Explorer and Knight of the White Orchid are likely to stand out compared to Smothering Tithe and Land Tax
Crumble to Dust If this set has as many 10-cent rares as I think it will, its going to have some $4 uncommons, or close to it
And then for a single green mana you can give it haste, trample, or reach for a turn, all of which have their value at times and further add to the reasons to play the card
