As soon as you defeat Keith, he leaves Bonz behind and Kaiba will ask if he would fight for him. He will accept. Bonz's best monster is the Snake Hair.
Completing challenge mode - Have Dark Magician, Dark Magician Girl, and Dark Magician #2. Level them up so that the Dark Magicians can use Dark Burning Magic. Equip Rageki and Mirror Force and Red Medicine or a Dien Keto Cure Master. You should not have a problem with challenge mode.
Defeating Egyptian God monsters - Send all Marshals against DarkNite (Nitemare). Have the first two monsters attack and have the third monster use escape (L). Repeat until the monster faints.
Defeating the Boss - Choose your best team/marshal, unless you want to use him to guard your base. If that is the case, choose your second best. Have your marshal move out of the way of your enemies until you get to the Boss.
Egyptian God monster use - You may only use the Egyptian God monsters once. Think carefully about when you want to use them. When you get an Egyptian item (Slifer's Orb, Soul of Obelisk, and the Eye of Ra), be careful when you want to use it, because you cannot buy it again from the trader.
