I was always a Free Kingdoms fan. Unfortunately the only Freek I was halfway decent with was Adaramy. But favorite of all time? Master Isl Loth. Despite being a Deverian and a wizard (my two least favorite things to play) he ended up my favorite Warlord and best deck I ever built.

I highly enjoyed each faction, but Nothrogs were my very first decks starting out.

Nothrog - Syvonne Ashenstorm was the very first deck I ever bought, but quickly I found Sargok to be more competitive

The Chosen - Naram-Sin I love the dual class ability and always had fun playing him

Mercenaries - The Nemesis I traded him away and forever regretted it because he was so much fun to play

Freeks - Beastmaster Eladric or The Lady of Mercy - I love both of their abilities and I love their flavor, they are so much fun

Elves - Morghen the Unliving - Creating Voltron was made even better with the second iteration of Morghen.

Dwarves - The Broken Earth - Such a fun ability to go along with my favorite subtype. No game is ever truly over with him.

Deverenian - Biana the Mystical and Commander Kaiten - The two I felt best embodied the "me" and "we" Warlords that Devs do so well.
