I hope you have looked at Splinterlands which runs on the STEEM blockchain. Gods Unchained is a hot topic here and has been for a while.
As a Magic player and knowing what Hearthstone is you will probably enjoy Splinterlands though its a more simple game.
Playing daily quests and getting FREE cards can become addictive. Welcome to the STEEM blockchain.
I will sure give Splinterlands a try, thank you so much for suggesting it! And yeah, I know getting free cards becomes addictive, heheh!
