Finally a bot exchanging cards and gems!

I was looking to trade my gems for cards, but it was really hard to find someone accepting offers fast or find a good price. There were trading bots everywhere, but none like this. 90% of bots were accepting gems only for whole sets.
So why not to do something usefull instead of spamming more and more trading bots with insane ratios.
I hope that you will make a lot of sets with this bot and also I hope for some positive feedback here, no errors and satisfied customers.
Gems4Cards bot will accept your offers ASAP. Feel free to add him, but send offers only via his profile please.
