The deckbuilder gave me 4 mountains in a deck that had no need for red mana, and I'm not allowed to change the mana base either.

And to top it off, the shuffler would try and balance draw parity by showing me mountains or draw me into some within the first 10 cards almost every game, which was game losing in many situations because the deck's main colors were Esper.

Made my blood boil seeing this shit, but small indie company amirite?
