Looooong time lurker; 1st time poster needing to know how Ghyrson Starn, Kelermorph and Furnace of Rath interact

Ghyrson Starn, Kelermorph

Not well I am afraid. No matter what is dealing damage, Furnace is going to double it so if something is dealing 1 damage normally, Furnace says it deals 2 damage. Ghyrson sees that it dealt 2 damage which is not exactly 1 damage so he will not trigger. The only way for them to positively interact is if you are playing with Un cards and attempt to do 1/2 (half) a damage which Furnace would turn into 1 and Ghyrson can trigger.

Thanks. That's what I wanted to hear
