Conquest is already synonymous with War, so it has to be pestilence unless you like being redundant.

Death is definitely the most interesting horseman. Make him the last one to fight.

Well you play AS the horsemen. And If I were going to do that, it would go in order, so yes, he would be last.

Irony points for Jesus, but otherwise, Pestilence.

I thought that as well. But it made sense when I read it.

Pestilence sounds badass in my opinion. It's a lot better than the other ones.

Well now that I think of it in SC terms, pestilence is definitely the right choice.

Pestilence - all about spell effects. Uses irrad, blind, etc. Most importantly plague.

War - no brainer, 2 ez. (would have too much in common with conquest)

Death - Trigger-based abilities like kill all units at location.

famine - will if supply has anything to do with it... also consume . also trigger based effects that drain energy or w/e.

Pestilence would also have to have, liek, a spawn broodlings spell of some kind. Either just spawning a queen to do it, or killing some number of units at a location to make some number of broodlings. The latter could be levelled up for win.
