Now, I know that this is not just bad luck, but also tactics on the part of my opponent. However, as mentioned in the halfling thread, it's not (just

What do people think? I can see this being more for the stunty teams so that dark elf assassins don't benefit. Let's face it, stunties (particularly goblins) are sneaky so it's just a little bit of cheating. I also thought that there is a built in penalty in that you'll be an extra player down.Secret Weapon (Extraordinary)
Some players are armed with special pieces of equipment that are called
‘secret weapons’. Although the Blood Bowl rules specifically ban the use
of any weapons, the game has a long history of teams trying to get
weapons of some sort onto the pitch. Nonetheless, the use of secret
weapons is simply not legal, and referees have a nasty habit of sending
off players that use them. Once a drive ends that this player has played
in at any point, the referee orders the player to be sent off to the
dungeon to join players that have been caught committing fouls during
the match regardless of whether the player is still on the pitch or not.
A coach may choose when to field a player with this skill, however,
and if he can field at least three other players to fill the Line of Scrimmage
may keep the SW player off the pitch and save them for a subsequent drive.
My other thought was an Inducement for maybe 20k:
Disguise
The coach has managed to buy an enchanted mask, or maybe just a really convincing wig that allows him to keep a player off the pitch for a drive even if it brings if it brings the fielded side below eleven players. The three player minimum still applies. The Disguise can be used for only a single player ONCE during the match.
