I feel only UR Delver can support the full playset of 4. BUG and Patriot are more mid rangy and cannot fill the yard as fast. When I have cruise in my opening hand I find that bug/uwr can cast it earliest around turn 4 while UR Delver can cast it turn 3 sometimes since they dump cards at amazing speed. Having 2 Cruises in opening hand means you have 2 cards doing nothing till turn 4. This is unacceptable in such a fast format.
