Just wanted to make sure about
(From the rulebook p.4: )
Advanced rule: If you want to have more control over the game,
each player may exchange their entire starting hand once,
before play begins.
The first starting hand is shuffled back into the deck, then 4 new cards are drawn.
1. Both players take their starting hand of 4 cards
2. Both players decide whether they want to play those cards
3. Then the Dwarf-player places his heroes
So the Dragon-player can't decide if he is keeping his 4 cards by the placement of the heroes?
