I'm not sure why are you comparing Silas to Inigo/Ranulf. My main focus are the 16 Hero Emblem from Cost 1 Kamuis. Silas as MC so that my Anya units can use Byakuya Kamui's Hero Emblem. The field isn't as weak as you think, with Gunter, Kanna M and Nowi at late game. And I have Cost 1 Eponie to check the top deck cards too.
I'm running seven other copies of my MC cause he's my MC. I need my evade cards. That's what my 6 Mage Emblem cards are for. For a chance to draw my MC. And also to discard Nowi so I can deploy her using White Kamui F. I'm using White Kamui F to deploy my Cost 3 Anya units, which require me to flip 2 bonds. I don't really have the extra bonds to flip for Clerics.
For Camilla and Beruka, although 30 support is good, their base attack is weak. Without attack emblem, their attack will most likely not go through. And SR Camilla needs CCS for the power boost. I find it not worth the effort as I usually deploy a Cost 3 unit using White Kamui F skill. That's why most of the units other than MC and Kamuis are Cost 3. Although ST Camilla is 3 Cost, But usually the ones attacking are Silas and Gunter, until turn 6. So I don't think it's that worth it to put her in.
An image of my deck might give you a better view of what's in it.
