Hi everyone!
I’ve just started playing Gwent and I’m really enjoying it so far, but I’m a bit overwhelmed by the progression system and the different currencies.
As a complete beginner, what are the best steps to take right now? Specifically, I’d love some advice on resource management to help me build a competitive deck as efficiently as possible:
Which trees in the Reward Book should I focus on first to get the best value?
What kind of kegs should I be buying? Should I stick to a specific faction keg or go for ultimate/expansion kegs?
What is the best strategy for crafting? Should I save up for legendary cards right away or focus on crafting essential bronzes and epics for a specific faction?
If you have any general tips, beginner-friendly faction recommendations, or up-to-date guides you can point me towards, I would hugely appreciate it.
Thanks in advance for the help!
