Sebastian.
Many, many times have people tried to run on my dog pack with say, Teddy, a "big daddy" (Mature Nephilim), or some other thing...to realize that when you don't kill him in one turn...you die.
He leads the pack, he can tear through lots of weak models with Bloody Harvest, and he is just nicer in combat.
But yes, it is a matter of taste.
It seems I am facing a losing battle of opinions, but I use Sebastian with everyone...even Nico.
Aside from that, I usually don't use anything but Canine Remains, Frankies, Sebs, some Punk Zombies and the Grave Spirit.
That's in....no need to fix what isn't broken.
Tag the totem along with a Frankie and run him in there as the leader of the squad of punks...Hard to Wound 2, 10 Wds and now Armor 2?
that's awesome.
