Fix Trade System

Sayrux

at first im okay with the limitation (same rarity,only up to 1 star)
after the update seeing how the trade work, this trade is suck

- you need to convert multiple card into token to trade 1 card
you can just make it cost more energy depending on rarity like wonder pick

- cant communicate with others if they have the card you need
make a chat feature so player can ask each other the card they need (sure we can ask on discord or something, but what happen to player that we only met on game)
or like someone suggestion, make some kind of trading hub where player can browse what others offer and need
