I had a small missplay
http://pastebin.com/PfvwzhKg
Silverfish is at V125.2, I hadn't updated it just yet.
On turn two, after having played coin + totem golem on turn one
Silverfish plays spirit claws, attacks enemy totem golem with my totem golem but then leaves it alive, it doesn't attack with the spirit claws.
I think it should either have killed the totem golem, or just attack face with my own totem golem and ignore his.
I still won the fight though.
Edit I really should have said that I'm not using the exact recommended settings, I'm using much lower maxwide (4500 instead of I think 6500-7000) and twotsamount (900 instead of 1300-1400)
