The following was in the last Gold Foil Press email I received from Splinterlands -
Riftwatchers - As most of you know, Splinterlands plans to release a new mini-edition of cards called Riftwatchers which is expected in Q2 of 2022. Riftwatchers will be very similar to the past mini-editions - Essence Orbs and AZMARE Dice - however instead of being exclusively available to purchase using DEC tokens, Riftwatchers will only be able to be purchased using SPS tokens - all of which will go directly to the SPS foundation treasury.
