idea: there is no real separation in the ranks, people just choose the rank as they want. how about the ranks are devided like this:
pawn: no upgrades or rares, but always get to go first, if the coin toss makes the opponent first, then they must do nothing on their first turn.
rook: no upgrades at the start of the game, if they win the coin toss, they can choose, once, to re-start the game, but can't do that again for the rest of the tournament.
bishop: (up to) six upgrades
knight: (up to) twelve upgrades
queen: (up to) thirty upgrades
king: (up to) sixty upgrades
