Survivor (or Seven Little Superheroes)
Build: a 700 point, 7 figure team - no more, no less than 7.
Golden Age or Modern Age (doesn't matter - venue's choice)
3 actions per turn (keeps the game moving fast, and makes powers like Leadership or free move TA's relevant)
Important: Before each round of the tournament, including the first round, one of your figures will get selected by your opponent to be voted off your team for the entire tournament (and vice versa). No Victory Points are awarded in this manner.
So for instance, while a team comes to the map with 7 members, the first round will be 6 figures on 6. The second game will be 5 on 5, and the last battle will be 4 on 4.
Survivor forces a player to build comprehensively, and not rely on one given strategy. Players are encouraged to avoid using Tentpoles - Cosmic Spider-Man would never see the map in this event.
Survivor also allows opponents to pick off the figure they think will give them the most trouble - OOTS Batman always a bother? Say Bye-Bye Bruce. Is Kid Zoom going to mess with your Nightcrawler? Kick the 'kid back to the future (but don't expect Kurt to stick around either!).
A well rounded build doesn't need to feature seven figures each exactly at 100 points - Gamora and Annihilus, for example, roughly total 200, as do Edward Nigma and Noh-Var (@ 201).
Depending on structure (Golden Age v. Modern Age) Feats are allowed to round out a team, though like any event individual feats can't be transferred to another figure. Should a feat require two people to work (ICWO, Sidekick) both must be on the board for the card to be in play.
I've run this event in the past, and seen some great teams. One player brought 5 War Skrulls, filling out the team with other Skrull Invaders. Another player fielded seven 100-point Sentinels, only to loose to the starter Fantastic Four (and their LEs).
Survivor is a fun exercise in team building, that offers plenty of room for comic accurate teams, with the JLA, Titans, X-Men, Fantastic Four, Inhumans, and many others featuring a number of competitive characters ~ 100 points.
For those really obsessed (like me) with the Seven Little Super-Heroes, here's a team you can build featuring the episode's line-up (with a substitution for the missing Shanna)
