Trading is so frustrating

Idc what people say about this but yall people need to realize it’s a GAME!! I understand people have their own strategy/goals for playing this game. The fact that some people are so stingy when it comes to trading cards is ridiculous. God forbid your one star short in a trade like it’ll make or break you. I have spent so much time looking for a card. The game has not given me any 4 star spares. Any offer I make isn’t good enough.
