Benjoewoo â€“ 5/5
Play this—it draws a card on a sacrifice cost which can net you multiple cards and trigger useful people like Vengeful Berserker. Will likely be phased out for decks that don’t want holdings, but card draw is few and far between now so it will be auto-include until more acceptable options for those deck builds come out. Even then, it’s a strong consideration because it can be done during any action window, and flexibility is good. 

Kingsley - 5/5
Long-lived card draw that enables your holding and sacrifice synergy cards? Sign me up! This is especially nice in dishonor decks, which often want to bid low and thus can use the extra cards

nyxnyxnyx - 5/5
As long as you have at least one character that has no fate and is marked for fate-removal that turn, it’s no big cost to get the card draw.

Grendel - 4/5
Has a lot of synergy with Crab’s sacrifice for value theme and can allow them to manipulate their bids in a way that can be long term punishing to the opponent. The trick is to balance having this sit out in deck construction along with your other low cost characters providing low value. I would look to crabs conflict characters and potentially splashing one.

I Fight Dragons â€“ 5/5
There is basically never a turn where you don’t have any characters leaving play, so the cost of funeral pyre is very negligible and it might as well say “Draw 1 card” every turn. It can run into timing issues however, when you want to use it but don’t have a bowed guy to throw on it, so keep that in mind when planning your turn.

Hey, Benjoewoo, what exactly is an action window as your refer to it ......

Even then, it’s a strong consideration because it can be done during any action window, and flexibility is good. 

I can't actually find it in the rules.
