I like control style decks. It's a carryover from my favourite Magic decks. My preferred FG/arena deck is rainbow control with hourglass/time mark. I like having lots of options in my play, and I dislike one-trick pony decks. In a competitive pvp environment, I'll pick whatever wins, even if I don't like it personally, but in pve, I'll pick fun decks every time. Thus, I don't like decks like Instosis or Splat, even though they do well, because there are essentially zero tough decisions to make.
In my rainbow control deck, I'm always making tough choices about where to spend quanta and what the opponent might do. Conversely, when two rush decks face each other, pretty much all that happens is both players dump their hands by turn 2-3 and put a brick on the spacebar. It can be interesting playing a rush against a stall deck because in that scenario, you have to make decisions based on what they might have to counter you with, but when it's something like monolife rush vs immorush, there won't be any decisions to separate the amateurs from the professionals.
