Djinn Oshannus has won me many battles on his own
As I remember, I have not tried this card so far. Would you recommend renting it? Is it worth it? Nowadays I am mostly in the Bronze Leagues, sometimes in the Silver III League, which is currently my max tier.
Within Bronze and Silver if you play water splinter this card is absolutely paying off. Now the price of it is down compared to previous weeks so i recommend to buy it, but the rental price is also affordable. I would suggest you to try it.
