Rivals of Ixalan brought a lot of fresh ideas and new cards into the Frontier format. In part 1 of the 2 part RIX set review episode, the podcast crew digs deep into the White, Blue, Black, Red, and Green cards. They discuss quite a few cards and talk about how they would fit into existing Frontier decks. This will easily translate into a must listen episode for people wanting to get into the new Historic format.
