Rivals of Ixalan was released on January 19, 2018, and contained 205 cards. It was the first Naturalize reprint after a hiatus of two years, and the only one during the Two-Block Paradigm, which started with Battle of Zendikar and endend with Rivals of Ixalan itself. Furthermore, Rivals of Ixalan was the last set being part of a block at all.
The English USA non-foil cards now look almost the same as their Belgium counterparts, the first ones had shown a thinner printed text. Generally, USA printed cards can still be distinguished by their slightly less rounded edges in comparison to Belgium print runs. All Rivals of Ixalan cards are front cut.
