[17] Prizma remained towards to the foot of the table during the 2016–17 season, winning 10 of their 30 games, finishing 6th out of 7 teams before ultimately losing in the opening round of the play-offs.

[18] The team would struggle during the following season in the newly renamed Optibet Hockey League too, finishing dead last having only won 4 games and failing to qualify for the play-offs.

[19] In the pursuing off-season, Prizma signed former Olympian and KHL player Armands Bērziņš, who had previously played for the team as a junior.

[23][24] During the 2019 off-season the team changed its name to HK Prizma/IHS in order to highlight its new partnership with the International Hockey School also based out of the Volvo Sports Centre.

They were drawn in Group C alongside KH Sanok of Poland, Romanian champions Corona Brașov and Hungarian side Dunaújvárosi Acélbikák.

[27] Prizma beat Sanok, but lost to both Corona Brașov and Dunaújvárosi;[28] as a result they finished last in the group based on goal difference and did not progress to the next round.
