Steam: Have you used the permentaly delete Feature?

[Fishbait]

Just got idlemaster, off topic but what do the trading cards do? I have maybe 200 steam games mostly junk but have always wondered what the cards are for haha

Sell the cards on steam, make money. Spend on more games or cards, icons, backgrounds etc.

If want easier life, Steam Inventory Helper can speed up selling/sorting etc. Runs in Firefox & Chrome.
