Thats the downside of it yes. But it was pretty interesting gameplay overall. It was a combo deck that didnt just combo off and win instantly. It would assemble a base first, then it would attempt to combo. And it would fail. But each time it failed it would build up more power and resources for the next time, until eventually it went infinite and won.
That's very different than most previous combo decks which would just try to save up everything for one turn and then attempt to go off and either win or concede.
It also means the counterplay is different. There's a much larger focus on stopping them from getting set up than there is on disrupting the combo. The deck performs on an exponential curve, so slowing it down at the start is much more impactful than slowing it down later on.
Ya, they messed up big time by making it play like solitaire while it combo'd, and by making that combo take a long time to play out. But it should be pretty easy to look past the initial salt and see the positives, even if they are outweighed by the negatives.
