SNIPE. You're right about the speed. But you're wrong about the Titans. Try playing 10 Titans against 10 Black Dragons yourself. Here's what happens:
Round 1: Black Dragon attacks and defeats 2 Titans, Titan attacks and defeats 2 Black Dragons.
Titan attacks and defeats 2 more Black Dragons, Black Dragons attack and defeat 1 Titan.
Round 2. Score: 7:6. Dragon attacks and defeats 2 Titans, Titan attacks and defeats 1 Black Dragon.
Titan attacks and defeats 1 Black Dragon, Black Dragon attacks and defeats 1 Titan.
Round 3. Score: 4:4. Black Dragon attacks and defeats 1 Titan, Titan attacks and defeats 1 Black Dragon.
Titan attacks and defeats 1 Black Dragon, Black Dragon attacks and defeats no Titans.
Round 4. Score: 3:2.
Black Dragon attacks and defeats 1 Titan again, Titan attacks and defeats 1 Black Dragon.
Titan attacks and doesn't defeat the Black Dragon, Black Dragon attacks and doesn't defeat the Titan.
Round 5. Score: 2:1.
Black Dragon attacks and doesn't defeat the Titan, Titan attacks and defeats the last Black Dragon.
CONCLUSION: There are 2 Titans left with 159 HP. I don't even think it's worth talking about how they would fare against Gold Dragons. It's all obvious. If there were magic, the Black Dragons would have won, but as it is... no.
Damn, I'm glad I didn't use a battle of 100 vs. 100 as an example...
