Durdle implies you're doing something though, even if it ineffectual.
Actually the definition he gave states it's doing nothing. (Not that this is necessarily the only definition of durdling). Landstill's "win cons" secondary purpose is winning the game, which is more what I'm getting at if you want a true durdle deck. Cards like Young pyromancer, and delver* are not durdle cards.
*why does my phone autocorrect delver to depver it's not even a word!
