Ferox is really easy if you use the nature version of this (basically same except with a leaf dragon and 2 jade dragons instead of light), because you can just use 7-8 RoLs and that is enough to stop his damage, and you get twice that in nature so you can fill the rest of the baord with dragons very quickly. I killed him that way even with him having 6 bonds out.
Edit: Just wanted to add, I alway use a luciferen in that deck so once I get enough dragons so that i have 12 total creatures I use to to elminate the Jade dragon damage, and be able to make 2 per turn.
