Summary: Since coming over from Kespa, Innovation (fka Bogus) has been the most consistent Terran in the world. He's won every major tournament you can think of, with the exception of Blizzcon, and has been a top Terran from HoTS to now.
Playstyle: A pure macro Terran. When talking about Innovation's playstyle, the word "mechanics" is going to be used in the first few sentences. His dead-perfect macro allows him to produce, expand, and get upgrades without skipping a fraction of a second while still having enough brainpower to micro his army effectively. No Terran in the world is better at getting more stuff faster than his opponent than Innovation.
He also has a well-honed sense for timings -- his attacks hit right when his upgrades kick in or his opponent is at a vulnerable point. Although he has occasional periods where his go-to build will be mech-based in TvT or occasionally TvZ, but Innovation's success has mostly come from having lots of units, perfectly placed, with perfect upgrade timings, with more units parading across the map to back them up and provide the killing blow.
Signature Unit/Build: The aforementioned bio timings. There are few things more dangerous in all of SC2 than Innovation at the moment 1/1, combat shields, and stim hit at the exact same time right as his units are about to engage the enemy, and if that push doesn't do the job he's going to come back right as 2/2 hits.
Weaknesses: Innovation's pushes are decisive. If he smells blood in the water, he goes for the kill, and will even pull his SCVs if he thinks they can end the game on his terms. The other side of this coin is that he can get a bit stubborn, and overextend on a defended push instead of going back home and transitioning.
He also isn't the best in the late-game -- when both players are maxed out and have money banked up, his best skills (getting stuff very fast and hitting timings) become irrelevant, and he generally tries to end the game before it gets there instead of going into Ghost/Liberator Range.
And while Innovation does pull out new builds from time to time, his "machine" label does make him a bit predictable. He's probably less likely than any other top Terran to throw out a proxy, he generally doesn't go for fancy drop play (with the exception of his early-game drop harass, which he uses to keep his opponent pinned and allow him to set up his 1/1 timing), and can show an inability to improvise, whether behind in a game or between games in a series.
That's Innovation -- the freight train Terran. You know what he's going to do, but good luck stopping him.
