Looking for name and special powers

On a lark I came up with a game that combines the variable powers of Puerto Rico with the die-rolling of Yahtzee. Players draft roles, roll dice and claim cards if their face up dice match the hand on the card (all different, exactly 21 pips, two pairs adding to seven, et al.)

So far the powers:

Go first
Gain a point when somebody takes a card you nominate
Score double points for a card
Reroll a die
Steal a die from an opponent, replace with one of yours
Go first in the next draft

Right now I have a thin veneer of Medieval Merchant as the theme. If you have any ideas for potential names or other ideas for powers I sure would appreciate it. Thanks a bunch.
