[Re: Barrel Behind the Door] You cannot activate 'Barrel Behind the Door' against effects if you don't know for certain that they will inflict damage when the effect is activated. So you cannot activate it against 'Dice Jar' , 'Judgment of Anubis' 'Time Wizard' or 'Ante'. Your cannot activate 'Barrel Behind the Door' against 'Ceasefire' if all monsters on the field are face-down or if all monsters on the field are face-up Normal Monsters but you can activate it against 'Ceasefire' if there is at least 1 face-up Effect Monster on the field. [Re: Des Wombat] 'Des Wombat' even protects you against card effects where the damage is undecided at activation like 'Dice Jar'.
