I think Ghostown is alot of fun with all the crazy abilities, while I find Jungo extremely boring and I don't like the SOA/SOB clans it just makes the gameplay feel less interesting, less to do. There's nothing that takes less brainpower than Roots vs Roots fights, at least Roots vs GHEIST can be interesting because its high power vs high damage
I think Dominion is surprisingly boring to play because you are forced to play certain cards at certain times, e.g. unless the enemy has SOA your Bugamon is either round 1 or you will use it for olding later
While Paradox is alot of fun with all the mindgames you play, it can be very unpredictable if you're not playing the boring cards like Dagostino Ld
I also think Berzerk is so much fun to play, not so much in tourney but in EFC, because especially with backlash cards like Sylvia Ld there's alot of minimums you have to think about that make the game play not obvious and all about disguising the winning round.
But with Xantiax Robb Cr it becomes extremely fun in tournament as well, its like playing with a nuclear bomb
What do you like to play guys? I know GHEIST is a very popular option because it has so many tricks with poison and growth effects and pillz manipulation, and people like the dangerous and damaging decks alot. People also seem to really like Komboka for the straightforward and high momentum beatdown playstyle
