Advice on my gladiator beast build march 2010?

Ok, first of all you need Elemental Hero Prisma, at least two copies. Since Bestiari is limited, you need another card to replace him so you can fuse into Gyzarus, and Prisma is just the card for that. Also, you're missing some X-Saber Airbellums for synchro summoning. I think you're a little low on monsters and kinda heavy on the spells. I'm not a huge fan of Savage Colosseum, I think Ancient Forest is way better because it doesn't put so much pressure on you to attack, especially if you don't have field control. Battle Manica is so worthless, all of the GladBeast equip cards are. You're opponent won't attack you if you're equipped with that, and they're already trying to avoid battling because of the way GladBeasts are already. Another My Body As A Shield is needed, and you should take out a copy of both Respite and Proving Ground, just because your so loaded with spells. You're missing Solemn Judgement in your trap lineup. And yes you should definitely try to get another copy of the War Chariot. I'm glad you already saw that Manica and Colosseum have cons about them.
