bone rider and a dark slime knight
great dragon + bone baron = black dragon any rank A monster + any dragon monster = great dragon grim rider + mohawker = bone baron
lethal armor + bone baron lethal armor + rip tide
sadly you can't find them , but you can synthesise them (Grim rider + mohawker) Or... (Grim rider + Dark slime knight)
You can synthesize a Great Dragon & Bone Baron later on in the game to get a Black dragon. http://www.gamefaqs.com/portable/ds/file/933956/50785 on this website it has the complete monster list and tells you how to get everything
Monsters that are synthesized by using high-level monsters with high ranks (Rank S, or A) usually produce the strongest results. It requires a lot of patience due to the amount of leveling involved, but it also needs the highest ranks so there is some planning required. There are walkthroughs for the game, but it is ultimately more fun to play through the game yourself instead of cheating by looking at the answers page. The strongest monster is either Dr snapped, dragovian lord, wildcard or ace of spades, but dragovian lord tends to be considered the strongest.
Well, I am not sure if this helps or not, but get strong monsters. If you are trying to beat her with three rank A monsters, that is still not good enough. I suggest a Black Dragon Rank S (Great Dragon+Bone Baron) You can look up on Wiki answers to find out how to get a Bone Baron and a Great Dragon. That could be the muscle of the team. The healer, another rank S, could be a Malaroth(Demon-at-Arms+Buffaglore) The third member of the team could be the Icuarnes or some monster strong. If you want really strong monsters, collect 100 monsters and talk to the man in Solitaire's office. He will give you a Liquid Metal Slime. I forget, but somehow I got a Metal King Slime from one of the people in the office.
Get S monsters, specifically you should get the Black Dragon. It is a mix of Great Dragon(obviously) and Bone baron(or something like that, definitely with a baron at the end and a rank A monster).Make sure you synthesize it with strong monsters with good attack, NOT HEALERS for the Black Dragon. I'm not forcing you to, but also you should probably get the Malaroth. There are two ways to synthesize it, look it up. No matter how boring it gets, train, train, train. You need strong S monsters. Good luck, and I hope I helped you.
Baron Bragg and the Devilish Dragon - 1922 was released on: USA: 24 September 1922
