Here is a Lucky Block capture the flag mini game! The goal of this mini game is to capture the enemy's flag three times to win! You respawn with 3 lucky blocks to try and get basic weapons and armor with. The map also has some chests filled with lucky block and some chests with normal gear. 
I would recomend 6-8+ people to play this map but if you want to you can play with 2 people

Note: I did not make the lucky block mod just the map and redstone
Note: you will need the 1.7.2 version of the mod to play
