Hope I'm not too late to the party.

E-mail or call the other players. Tell them what the DM told you. And remember the golden rules.
Rule 00 - The GM is Always Right: If he changes the RAW to negate tricks, that's that.
Rule 000 - ...But no Players Means no Game: But just because the DM holds the most power doesn't mean he can be a tyrant. It is well within the group's rights for everyone else to leave and start their own game.
