I played many card games. Played Yu-Gi-Oh when I was a kid, then because of my love for Warcraft, I played Hearthstone for years. Then because of my love for the Witcher, I started to play Gwent. At first I thought that how would I get those cards to make a decent deck but thanks to the generosity of Gwent, I made my first decent deck scond week. I realized I worked like a slave when I was playing Hearthstone and loved Gwent even more. At those times Rank 21 was the best rank and I was 20 (never hit 21, sadly) with my own deck. It amazed me that I didn't need to netdeck streamers to win. After patches and the other stuff Homecoming came. At first I didn't like it, I wanted my old Gwent back. Like everyone else. But when I tried to like Homecoming, I realized that it is not different than the beta version at all. OK there are many changes, but after this last mulligan update it literally started to feel like old Gwent, with better graphics and rewards. TL;DR: Gwent is the most generous card game on the market (literally got full collection and most of the premium cards without spending a penny), and you can play with your own deck instead of netdecking and still can win.
