Two-Headed Giant for any of these formats is also sanctioned.
Some other ideas for constructed tournaments we could run are:
Peasant - No rares, no more than 4 uncommons Highlander - Only one of each card other than basic lands, minimum of 100 cards Prismatic - at least 20 cards of each color, minimum of 250 cards
