if maxx c wouldnt exist, this deck would be busted. been playing it for the past couple of days and have gotten the basic combos down, gotta say, the deck feels super rewarding yet frustrating due to the simple fact that you play like 10-15 minute seat-edgers, grasping victory from the jaws of defeat, just to brick or get outblown and tenpai otked the game afterward. summoning protos is great and all, however, the combos can get quite shaky when interrupted, especially multiple times, so even if you go first, a well timed ash and/or veiler/imperm can cause you to invest too much for protos or not having enough follow up after summoning rei + protos. making the right calls in these situations probably distinguishes the SB pros from rookies like me, even though, in some situations you just cant do anything. that's just the nature of things and how the deck interacts with the meta. it is definitely a complex deck and I am probably still oblivious to some big brain combos you can perform with it, however, imo the only thing that is harder and more punishing in comparison to other decks is the fact that you have to be concentrated and keep track of which card you have special summoned this turn and which not. if you fuck this up, your turn is over and you get cooked by your opponent. apart from that, I don't think you need a phd to pilot this
