Card in hand

#MetaGame

To improve the strategy in the game, we discussed a lot and finally decided to make the equipment cards in the hand, like the game Hearthstone and Clash Royale. I was responsible to development the equipment system and I finished the functions of card supply and arrangement. I also put a weighted randomness generator in the script so that I can adjust the strength of the equipment in the different time during the game and make sure there will be all kinds of equipment in the hand.
