MCTS shuffle is wrong

state.players[k].shuffle_deck()

# the mcts rollouts don't randomize cards that have been seen with Index
        indexed_cards_in_deck = []
        # print("mcts print: %s" % (state.players))

        if len(state.players[k].deck) > 0:
            while len(state.players[k].deck) > 0 and state.players[k].deck[-1].deck_location_known:
                indexed_cards_in_deck.append(state.players[k].deck.pop())
        for indexed_card in indexed_cards_in_deck:
            state.players[k].deck.append(indexed_card)
# and "imagine" a scenario for the opponent - this assumes knowledge of opponent decklist!

state.players[k].shuffle_deck()

This currently looks at my deck, finds the cards that are indexed, puts them in "indexed_cards_in_deck". Then it takes "indexed_cards_in_deck" and puts them BACK into my deck.

Then it shuffles the deck.

This code doesn't do anything.

More specifically, it just hurts the AI because it will not actually know the location of the cards it should.

state.players[k].shuffle_deck() should be 4 lines up.

+1, this MCTS needs to remember what it knows after casting Index
