Tactics for Rampart.

In the Rampart (in my opinion), the best units are Pegasi, Dendroids, Elves, and Dragoons. I can't seem to accumulate enough Centaurs (they get taken down too quickly); Gnomes used to be effective, but now they're not very useful; there aren't enough Unicorns, but they are strong. Pegasi take down enemies quickly (and are also taken down quickly); Elves are excellent archers; Dragoons are level 7, so how can they be bad? Dendroids are strong, but they take a while to get there...
