The Ent Card Set is listed as */7, however the tiers unlock at 3/5/8.
Both the Abomination and Amaranth Card Sets are listed as */8, but I’ve only ever encountered 7 creatures that belong to these two races, nor can I find any reference to an 8th creatures for these races in any known online list. Do these 8th members of these races exist?
They both just have special monsters that aren’t available yet. In S3 the abominations had the cloth abomination and the amaranth had one that was like a Christmas wreath.
It could be the same or something else.
Several races are like that, they have holiday or event creatures as well.
