I finished in Silver I last season with 18 rewards chests to open. A gold foil Gargoya Lion isn't the greatest card but a gold foil nonetheless. But it is the 1 additional pack that was the highlight for me.
I opened it immediately and look what I got... a Gold Foil Legendary! It is for the Dragon Splinter that I don't play with much. Also, unlike the Gold Foil legendaries of old, this is worth only 12,500 DEC which is like a Gold Foil Epic previously.
It does put me closer to Gold III although I am still about 10k DEC away from the target. Think I will be able to make up the difference this season if I buy some more packs and earn more by playing more.
