I took a gamble taking "Extra Glyph" hoping for some way to break walls. The alternative would've been a Binlor -> TT or Binlor -> JJ prep/conversion, but I didn't particularly fancy either, given how much I dislike prepping Binlor in general.
In any case, Extra Glyph is probably one of the best preps today!

I was so proud to see all those little Berserker pups all grow up to be mighty, broad-shouldered, bloody-bearded warriors, and so I provided them with the greatest honour: I volunteered to be the opponent for their customary rite of passage duels...
"Thinker", just without the "ache".
