I just added some stuff to the attack/block code
1- The block bug should finally be fixed. The problem was that it was looking at whether there was an enemy in the enemy slot with the same number as your defender slot, and not the slot you're defending against. So if there was no enemy directly across from your monster it would fail.
2- attacking and defending is now more verbose - it should say the names and slots of attackers/defenders if the attack/defence command succeeds
