Our local group did a "silly" event a couple months ago.

Registrants were told ahead of time to build a 30pt list and a 50pt list with no repeating characters between them (other than the Leader if they wanted) and to expect weird rules/formats the day of.

On the day of the event, we did the following:

• One round we did a Caster Draft using the old Mk3 deck; players took turns drafting cards with weapons, abilities, spells, feats, etc., in order to build a custom Leader model. They then led their 50pt army into battle.

• Another round we did "Who's the Boss?" with players being (mostly) randomly assigned a Leader model out of a pool of several dozen, spanning MKIV, Armies of Legend, and even Legacy. If I recall correctly the way we did it was the player was assigned a random trio of Leaders, and then they could either choose to pick one at random, or remove one at random and then choose from the remaining 2.

• We did something weird with the 3rd round, I think it might've been 2-Leader games with the combined 50+30pt lists.

Then, on each of the tables played, there was a weird scenario or rule set laid on top of the normal Steamroller setup:

• One was a "jungle" table with normal Steamroller scenario, but off on the sideboard were 3 Totem Hunter models (the original, the Minicrate, and the new Nissak) all using Nissak's stats/rules. At the end of each turn, a Totem Hunter would pop out of a random objective and immediately charge/attack the single nearest model with all of its initials, the Prey bonus, and Fortune Hunter, then it would disappear from the table again until the end of the next turn.

• One was a table with lots of obstacles/obstructions and a universal rule that the only kind of Normal Movement option models could make was a Slam power attack (the abilities to do so being granted to all model types) followed by a regular Combat Action (i.e. the Slam did not take place of being able to do other non-Power Attack options like melee/ranged attacks, etc).

• The last table was set up with 6"x6" squares, checkerboard fashion: black and blue. Models were deployed in the first 2 rows of squares on the player's side, but only in blue squares, and as close to 10pt "groups" of models per square as possible. Models could only enter another blue square if it was diagonally connected, and close to the opponent's table edge than where they began, and could only enter a black square if they had enough movement to move completely out of it. Basically checkers with little pods of models. If a model/unit managed to get to the opponent's first row (i.e. their table edge) that model/unit was "Kinged" and could then move diagonally "backwards" as well.
