Hi, well first of all i think you shouldnt use ultimate offering since it conflicts with the scout, if you want to use offering then take out the scouts and test the corrosive contagion infestation, i thinkg the recurring nightmare would be better maxed out, never liked the hercules myself but if you like it try the infestation ripless, personally i would use the infestation pandemic infection instead of dark iullsuion, since it protects all your steelswarms at once, hope it helps, remember this are just ideas if you like try them but lastly its your deck use what you think works better with your style =D
