Yes, it is expensive—and for me personally, it cost a bit more than usual—but its performance is quite impressive, especially when the 'Bloodline Tribute' is active, granting +1 to the stats of all cards sharing that bloodline. Based on my experience so far, I’ve concluded that it is better to rent cards rather than purchasing them outright; this allows you to enjoy them for the entire season while simultaneously putting them through the most thorough testing possible.
