Disclaimer: My decks are built to be fun and not that much competitive.
This is the deck I've been playing pretty much since I started playing Eternal and is one of my two favorite decks to play. This is built upon initial feln theme deck I got when starting eternal and then changed a lot of cards from that on.
It's a rather simple deck but it works in a lot of cases.
To some it may even seem too inconsistent but try playing it - it's fun.
