Just curiosity to see what people usually plays (real or virtual decks) and how they go with each...
I will start just for the example... all decks here i use at gccg but i got them (almost complete) in real card version as well...
Rainbow Freeps with Corsairs: Probably one of my best decks, this freeps never get killed in a game and i lost very few times being not able to stop or kill with shadow. usually goes for a freep win but corsairs...well...you all know them

Dwarven and Gandy with Morcs: This one's strategy is very simple: stay alive with freeps and build a shadow kill... usually it works pretty fine, but sometimes, depending on matchup and draws i got killed before i kill. I can't remember many people that reach site 9 alive. This one also have a good winning ratio.
Gondor and gandy with Sauron GROND: Freeps are ridiculous hard to kill after they set up and shadow is a pretty annoying one that keep freeps naked with grond and minions that discard conditions to prevent them from running and making them vunerable at the end. Doesnt work 100% of time but is very solid.
Rohandalf and Southrons with grima twist: Freeps depends heavy on the matchup, my winning ratio is not that good cause my freeps usually gets killed against a bad matchup (corsairs, enduring guls, etc) but i really like the shadow!
Hobbit crazy choke with Dunland site control: Probably the most "matchup-dependant" deck i have. Against certain decks its an auto-win or auto-lose, but i like the choke concept (and how its annoy my opponents ;P)
Well, thats it for now!
hope to read yours!
