I didn't say that
Grudj is more useful than
Bogdan. I said that
Freaks lists that don't have both
Grudj and
Bogdan are lousy.
SOA is great but for almost all SOA characters, turn 1 is the least effective turn to play them.
Grudj doesn't fear SOB because he's carrying pill manipulation on his ability- he's a double threat. If an opponent plays a SOB on
Grudj, it's really a win-win: either you won with
Grudj and gained 2 pills, or you lost with
Grudj, in which case your opponent wasted his SOB character.
This doesn't even consider bonus SOB, in which case
Grudj is clearly superior on turn 1. If you play
Bogdan on turn 1, your opponent will simply dump their 2* SOB, (or
Tyd) whereas +2 pills pressures your opponent into pilling.
Against combat abilities, again you would often rather have
Grudj. Blind, on turn 1, +2 pills is a better "combat" ability than SOA.
One of SOA's most important uses is to hit through DR. Not only is this not as useful on a poisoner and almost never relevant on turn 1, but
Grudj dominates DR just as well.
There are many initial draws where SOA isn't useful on turn 1. +2 pills is far more often useful on turn 1.
When I draw one and not the other, I will sometimes wish I had drawn
Grudj instead of
Bogdan on turn 1. I have never wished I drew
Bogdan instead of
Grudj on turn 1.
On paper it may seem SOA is a better ability than +2 pills, but my empirical experience tells me that
Grudj is a slightly better character than
Bogdan.
