I haven't played Splinterlands for aaaaages. When I played there were no guilds, and no potions, and... your screenshots of the game look so different to what I remember, haha.

I'm not sure I'll be much help!! But when I played, I personally looooved the Life cards. That was my favourite "element". I'm not sure if things are still the same, but my general strategy was melee characters at the front, ranged at the back... my very first character and very back character had the most health also. I found that advantageous.

It's probably not tooooo late to get into it. 🙂 Though I'm kicking myself very hard for selling all my cards ages ago. 😵😅
