Nemesis Theme from ETCO | and yes its related to Eschatos

[Dokutah]

The theme’s name is tentative, because this theme’s cards do not share naming with the “Subterror Nemesis” subset in the TCG. Meaning they have no interaction with those cards.

Could this be the level 11 supplement like true king for 9 and dragon ruler for 7? Sure hope so!

I wonder if the Level 1 EARTH Rock (700/0 ATK/DEF?) is gonna search out their Spell/Trap support.

Kinda wish there was more to 'em though; they feel a bit underwhelming like Elementsabers.  Corridor could be useful just by virtue of being Level 4 and a Thunder though.

[Atypical-Abbie]

I don't get the names Flag, Umbrella and Corridor, what kind of monsters names are those and how does it relate to anything? Regardless, I like that we get a theme similar to Elementsabers, but their own thing too, though it's a little odd that to get the small guys out, you need something banished first, meaning you need the big guy out, but then you are going to be using your monsters to do that, so you don't have a lot of monsters. I suppose mill tactics are going to be a thing in here, though right now they lack that. I like that they use Level 11, probably not gonna be more than those 2 though, but I can wish for a proper Archetype one of these days.

Both Eschatos and Protos are Amazing!

But the Minions have no playability in the deck until after the bosses come out.
Which makes them a moot point.

I guess the only Deck can run them perfectly is "Fur Hire", or Decks with tons of handtraps

Corridor is basically a Collosus for everybody. i dont hate it, but it feels somehitng will go wrong with these guys
