Joining guilds: good for knowing people, earning merits (and sps in the future) through brawls, make experience (more battles)
To power up: well, it is not that easy. Rewards are random and so it's a matter of luck, and money. Make some experience by playing and start purchasing cards according to your budget, today crypto are not expensive as 1 yr ago, so any investment is cheaper (but we can never say if they go much lower in the future). For sure Chaos Legion and reward cards are getting cheaper and cheaper until all packs are sold, so a good idea would be to focus on buying those a few weeks before packs get sold out.
Some common/rare reward cards are quite strong when leveled up, but you still to level up summoners which are more expensive. If you focus on 2-3 colors, you can easily farm with those and slowly slowly getting stronger also with the other ones. Time will be your friend, rushing will be your enemy.
