Like many others, I have trouble against the combinations Scarred LLama mage with Flesh Golem or Kron the Undying.

In [Reverse Speed] mode, when I knew the opponent was going to play this build with Flesh Golem, I decided to go with slow attackers and the outstanding ability of Halfling Alchemist.
The goal was to have a high miss rate from Flesh Golem, due to the Last Stand ability from Scarred LLama mage , which increases all stats of his monsters by 50%, including speed, which in turn decreases speed in [Reversed Speed] mode, but also decreases accuracy. You can find a short explanation in the following thread Click.
Halfling Alchemist's Halving ability should further prevent Flesh Golem, as it halves the attack power of a hit monster.
Working with Stone Golem and Wood Nymph, I now had an insurmountable wall, so despite its high life, the enemy Flesh Golem finally defeated itself thanks to my Mylor Crowling's Thorn ability.
I think it's a pretty special and situational setup. However, I think there is a certain transferability. It might at least make it easier to deal with Scarred LLama Mage and Flesh Golem.
