Nice Recap!

Battle 1 - Yep you start to see a lot more "ignore the front line" type strategies in gold and it's even stronger in Diamond / Champ since Baakjira is basically impossible to defeat. Better to play sneaks / opportunity to take out the supporting cast.

Battle 2 - Vulguine is really strong in gold / diamond and once again you want to avoid the front line (pelacor conjurer) and attack the back line! CrystalSmith isn't worth it with no healing ruleset! :P

Battle 3 - Loan Boatman is pretty good in gold and insane in diamond / champ once he gets shatter. Warrior of peace definitely a good call in rise of the commons since there won't be much magic damage!

Battle 4 - LLama + Merc works well in blast, noxious fumes, and earthquake but in other battles the cripple from acid shooter can shut it down in most cases with a proper team!

Battle 5 - Cursed Windeku is a good call in that ruleset!

Thanks, I learned a lot!
