It's a topdeck Tutor like LDV and the disadvantage adds up especially under considerations of spending Rituals or Petals to cast it in the first place. Other storm variants don't use LDV to Tutor for Ad Nauseam or PIF due to that reason. The Problem is that you create real carddisadvantage by casting Doomsday and try to resolve the Spell what makes up for the disadvantage after you already pushed all-in ... with less cards in hand to protect that spell or draw into the pile to begin with. If you use LDV to Tutor DD that's a whooping Virtual mulligan to 5 in regards to cards compared to your opponent and I doubt a compeditive deck can allow itself to do this even if we ignore the other problems (in particular: the storm iteration)
