There’s also a new Trap Card for Eidolon: 魔法名-「大いなる獣」that has a forced reading.

魔法名-「大いなる獣」 Note confirmed name but it looks like “Magical Name – “Great Beast””
Normal Trap Card
(1) Target any number of your banished “Eidolon Beast” monsters (up to 1 card with the same name); Special Summon that monster in Defense Position.

A correction:

Cocytus has 1800 ATK not 1000 ATK.
