Each set of these cards gives you 100xp, So your total xp increases by 2,000 after crafting these sets of cards and boom you go from steam level 10 to level 20 Requirements: You need to have an unlocked steam account ($5 spent on games or anything) Note: If you need to achieve a higher level (More xp, more sets of cards), you can text me
