We all build lists when we play Warhammer 40K. It's part of the game. Finely crafting those points to fit as close to perfectly in the allotted army size, balancing the types of units to fit within the detachments, sacrificing weapons to allow us to bring one more body on the field, it's an exercise in mental mathematics and pre-planning. Some of those lists become favorites of ours and, through tweaks and tests, become highly honed in destroying our opponents! ... But then something happens. A new codex comes out, a new edition comes out, a new supplement comes out, whatever it might be, suddenly our beloved list is obsolete. What do we do then? Well Phil, the Glacial Geek, gives you his thoughts on the way forward when your list suddenly can't be played anymore!
