Haha, I know...Ice Pixie is almost always just target practice for my opponent. I just couldn't believe how this one turned out haha!
I did rent a few cards last season. I rented two Gold Legends to give me enough Power to qualify for Gold III (and even won a game there but for some reason SPL clawed by my chest rewards to the Sliver I level - I was pretty angry because it was a waste of time set of reward chests anyway, almost all potions). Then I decided to get fancy and rented a couple of power cards I thought would help me win battles, but I am not good enough to win a t gold even with Chthulu and the Prismatic guy combined haha. And it gets really impossible to anticipate what an opponent will play when you have never seen any of those cards before and have no clue what happens to cards at L2 and L3. All told, I spent 220 DEC in 1 day to power up and lose a lot, and got less than that back in season rewards.
But, I will probably rent some cards to maximize the level I can get to before the end of the season hoping that I was unlucky last time.
Yeah, Cthulhu and PE are both high mana cards. I can see why it may be difficult to get a lot of use from them.
