The Legend-class Tretta for this set features Mew. Standard Tretta are colored a dark blue called "deep river blue". Special versions of Reshiram, Zekrom, and Kyurem were introduced in this set, all versions of which have an Absofusion () icon. Having either a Reshiram and Kyurem or a Zekrom and Kyurem with these icons still useable in Round 3 of Battle Mode will trigger the fusion of these Pokémon into White Kyurem or Black Kyurem, respectively. The move available to the fusions depends on the class of the Pokémon used to make it. Using two Master-class Pokémon will result in a White Kyurem with Ice Burn, or a Black Kyurem with Freeze Shock, while any fusion that includes a Super-class Pokémon will result in a White Kyurem or a Black Kyurem with Blizzard. Triggering the fusion will fully restore the HP of the resultant Pokémon. If the player has all three eligible Absofusion Pokémon still useable in Round 3, the Reshiram or Zekrom with the lowest HP will be used.
Tretta with a Secret Ticket were also prominent in this set, and made more explicit with the use of a icon present on the reverse.
The Search Mode locations have a winter theme in this set, and all remain the same as the previous set.
