Here are my predictions that include a brief synopsis of each player. Good luck to everyone competing in Las Vegas this weekend.
Biohazard - Biohazard uses Bane and Harley at a very high level. He has recently added Deadshot to this deadly duo and I like his chances to power bomb and shoot his way into the top 16.
Dragon - Dragon is the best Aquaman player. He plays a highly defensive style that will challenge an opponent's patience. Dragon also has access to Poison Ivy, who could be effective in some matches. I expect a top 8 finish.
Forever King - Forever King is the best Batman player. He also uses Black Adam at a high level. If alcohol consumption and losing shoes are no concern this weekend, I expect him to place at least top 16.
Forever King Jr. - Forever King Jr. uses Bane and Black Adam at a very high level. In particular, he plays an aggressive Black Adam who is heavily based on frame traps, set ups, and 50/50 mix ups. I think he does very well this weekend and places top 16.
Foxy - I am not sure what occurred at CEO, but I know that Foxy has a competent and efficient Catwoman. He usually performs very well abroad and under pressure. I expect a top 16 finish.
Illusions - from what I have seen, Illusions has the best Green Arrow. I am of course also a huge fan of his Cyborg, whom he uses very efficiently to counter pick Aquaman. I hope he shoots and blasts his way into the top 16.
Perfect Legend - Perfect Legend would of course be the first player to find the character who plays the most similar to "Bird Lao". I speak from experience when I say that his Brainiac is very strong. Not too many players will be prepared to deal with the aerial movement and the dive kick madness. I think he places top 16.
Revet Leafing - Revert Leafing is a wild card. Actually, Cheetah is. I think he can make a deep run in this tournament depending which opponents and characters he fights. He has no secondary characters so he is going with Cheetah all the way.
Rewind - Rewind is tied with Tekken Master as the best Atrocitus player in my opinion. The hype over Atrocitus has somewhat declined recently because of Black Adam's, Catwoman's, and Scarecrow's success. Will Rewind be able to defeat an army of Black Adam, Catwoman, and Scarecrow players? I think so. He will defeat enough of them to place top 16.
Semij - Semij is the best Catwoman player. If I remember correctly, he has won the previous three War of the God tournaments and beat various high level players from the Emperor clan in the Kinetic versus Emperor clan war. If he remains focused during clutch moments, he can win the tournament.
Slayer - Slayer is arguably the best Black Adam player who also uses Aquaman and Superman at a very high level. He is another player who could win the tournament.
Sonic Fox - Sonic Fox is still the favorite to win. He uses several top tier characters at a very high level but can also use a couple of low and mid tier characters, such as Captain Cold and Joker, for match unfamiliarity.
Tekken Master - Tekken Master is tied with Rewind as the best Atrocitus player in my opinion. As I have already stated above, the hype over Atrocitus has somewhat declined recently because of Black Adam's, Catwoman's, and Scarecrow's success. Tekken Master finished second at last year's Evolution so he is more than capable to place top 16 in this game. He is certainly more experienced.
Theo - Theo is one of the community's strongest fundamental players. He is best Superman player who uses Aquaman as a secondary character for a couple of Superman's more difficult match ups. He could win the tournament.
White Boy - White Boy displayed phenomenal d+1 and command throw mind games, impeccable footsies, and endless patience when he won the CEO tournament with Scarecrow. Opponents will be more prepared to fight Scarecrow, though. Nonetheless, I expect a top 16 finish.
Wound Cowboy - I know for a fact that thus far Cowboy does not connect with any character as well he connected with Sinestro and Shinnok. I still believe that with some luck he can place top 16. He uses Aquaman, Black Adam, and Dr. Fate effectively.
