Okay so let's take a look at Tithe Collector:http://infinite-network.com/card/tithe-collector
Okay so some things. First of all this card needs to lose its unique status. The ability is not that good to warrant that, and it's not like he or she is named. So it was obviously some kind of ploy to stop it. However, its unique status and two purity and low health for a relatively high resource cost and moral cost is just really... poor.
So while I don't want to try and overhaul the card from scratch I want to point out a few bullet point changes to actually make this card useful. Not all of these have to be done, but I think one or more would be a good idea, so all these should be treated as an and-or kind of thing.
-Up his health. The card can be killed quite quickly and unlike most flame dawn cards his attack also sucks. This means it is killed quickly, which there are many ways to do it.
-Take away his unique status. At 4 cost it's really not like people will spam all three in one turn. It's not named and it's some weird balancing decision. With all the cards that hit into the support zone it's not like he stay there with impunity.
-Lower the moral cost. He's as easy to hit from command as a wealthy noble and costs just as much but has twice the cost.
-Make his effect work from command. Why have him deployed why not put him in command? I'm not a fan of this one because it'd be pretty cheesy to put three in command zone. This one kind of precludes that it keeps its unique status.
I really think the card needs a change to make it useful and not just a speed bump.
