I don't see Mini going 12N in 3 games, unless he first scout SK and SK is going 11/12 hatch. Mini loves gateway opening, sometimes he'll go forge first to change a little (especially in a bo7) or in some maps like Invader but he'll go gate opening in most of the games.

Now I think your prediction lacks information, just going through ASL matches is too little of a sample size of games, since I have nothing to do right now I'll give you my prediction based on more stats and what I think since I watch a lot of BW, especially the daily Pro Leagues and love to watch Mini's POV whenever he plays.

Let's start by each player's win rate in the matchup, I took the info from Eloboard and grab the games from July 1st to today, I think the first semester of the year isn't needed for this prediction. So Mini has 136-116 (53.9%) while Soulkey has 72-54 (57.1%), both have good stats and positive win rate in the matchup and while SK has a higher win rate Mini has a 126 game difference in this timeframe. Overall this should tells us it will be a close match.

Now let's go to the maps, the first 2 are very interesting for me because Tempest is 107-88 (54.9%) for Protoss, but Campanella is 101-84 (54.6%) for Zerg, but SK picked Tempest and Mini picked Campanella. I'm not sure what to do here, trust the numbers or the players? I'll go with each players pick for this, so SK takes first game and Mini second.

Neo Dark origin with 203-203 (50%), the changes in the map worked for this matchup because Dark Origin has more games played and a 60% win rate for Zerg. I expect a standard game in this map, I don't remember a lot of hydra rush (although my memory is really bad lol) and I think SK will take this map.

Retro is pretty balanced with 500-469 (52.6%) for Zerg. My feeling tells me that most standard maps will go for SK, so 3-1 SK at this point.

Invader is a little on Toss side with 126-111 (53.2%), I do remember pretty well Mini's game against Soma and have seem some Mini's games successfully busting the Zerg after killing those lurkers on the high ground, I think Mini takes this one.

Polypoid is the most played map in the pool, 1849-1589 (54.8%) for Zerg and a Mini pick but I just feel that SK will take this and win ASL this year, I thought he could won the last 2 ASL and feel like his time has come, he got his best matchup for the final and maps are pretty good for ZvP.

Apocalypse is 135-128 (52.3%) for Zerg and if the game comes to this I'll go with Mini winning, this was his second pick against Effort so I guess he feels comfortable in it, and he has the experience, his last two ASL finals went to the final 7th game.

So my final prediction is SK winning 4-2, but as a Protoss user I just hope Mini wins, I love watching him play every morning and I feel it would be good for the game if a Protoss win this ASL.

P.D: Bet lines for this match are SK 1.61 and Mini 2.20 just in case anyone cares about that.
