bases commons cost more than crate ones when it comes to quantity for 1 common its 3k but for 6.5 k i can get 4 cards instead of 2 and for also it cost way more for 15 cards than it does for crates and you get a few rares and an epic from crates also ive seen youtubers like fire water without base and it seem way cheaper for leveling power kits
The rares cost 18 k man while i can get those for 6k with crates
