Horse Emblem Help Please

I have Reinhardt, Cecilia, and BLyn
I was using Xander but I have an Eldigan with +atk-res and another with +res-hp
Xander is strong, but would a DC Eldigan with +res destroy? I really dont know but feel like he could really blow my Xander's compariability and viability to him outta the water.
The input is greatly appreciated.
