In this respect it leaves plenty of scope to make the deck your own, which is not a bad thing necessarily
Theres Midnight Clock, Thopter Spy Network, Court of Ire, and (if youre a maniac) Descent into Avernus
While the "ease of flipping" category is, in large part, a product of the number of defense counters on the battle (battles range from three to seven defense counters, and a battle with three defense counters will be much easier to flip than one with seven), it also takes other factors into consideration, like whether the battle makes creatures (if so, we can use them to help defeat the battle, making it easier to flip) or whether the battle acts as removal (which can get a blocker out of the way, making it easier to attack and defeat the battle)
I think even ignoring the Arcade, Dusty Parlor seems worth a shot in plenty of decks
