50 point pSevvy List

[Nefarious60]

So I'm signed up for Hardcore at GenCon, and this is my 50 pt pSevvy list, criticism welcomed.

pSevvy
-Blessing of Vengeance
-Reckoner
-Dervish
-Vanquisher
-Hierophant

6 Choir of Menoth
Exemplar Errant Seneschal
10 Exemplar Errants
-Officer and Standard Bearer
Reclaimer
Rhupert Carvolo Piper of Ord
The Covenant of Menoth
Vassal Mechanik
2x Vassal of Menoth
Wracks

The main things I am considering changing out are the vassal mechanik, and the castigator, to get a bit more stuff to bring down heavy armor as I can see that being a HUGE problem for this list. Like I said though, any advice is appreciated.
*EDIT Changed castigator out for Reckoner.

[SgtPepper]

Change out the Castigator for a Reckoner for starters
