Top 4 files and analysis.
4th place- Khiruki
Khiruki expected a lot of damage based files and little to no removal souls since four soul cards had to do damage. Zu would be easy to get to without soul pact and would punish rush files. While ellie could slow down a ton of files and pick off several units. Annrose and Zugateroza proved to be an endgame to reckon with when Zu was off the board. Good card choices and a solid strategy, the slash units also had use.
3rd Place- Deng777
Gowen was the most common file as expected, but deng's had great consistencies compared to others. Sakura, Bringer, Revolver and Dilate proved useful against pretty much every file. Athira shin and the 2 EX mercenary girls were also great choices since big files were expected. Gunslinger and the grimiores were great at slowing down rush files as well. The damage soul cards also helped him gain control in the mid game.
2nd place- Angelspawn (dreamspawn)
Using removal soul cards proved to be a great strategy since a number of files didn't bother preparing to see them at all. One soul that does damage and can remove two cards was an excellent choice. The beefy level 2-4 units held up well and also had a lot of agi and atk thanks to amazon and toromea. After rozly and heierrat army/horseman it was a very quick set up that could maintain field presence with raw base stats and the nue/sun god combo. The lucia and tierie also covered the AoE damage that was expected from the big files, mainly big red.
1st place- Gabotheplaya
Most people didn't expect to run into a single mono falkow file since they lacked damage grimiores and function well with soul cards that don't do damage. Gabo's 6lp lvl3 Wizard Kingdom file proved that falkow could still be a force without returns. It was a simple high agi field control wk file with a ton of revive at the end game to secure wins and not run out of his 4 main units; Mage knight of regus, EX wizard soldier, Regus combat sorcerer, and Elite fencer of regus. A lot of great tech like storm wizardess and Sorcerer monk of regus were also handy near the mid and end game stages that clinched him wins. I think this is a pretty good example of level 3 wk. A few main units with a ton of tech units.
