Talk:Pulling the Rug

i'm still not clear about this card. How if i attack one facedown monster and the monster is (example) man eater bug. can i use this card negate the flip effect and destroy the monster? Or how if there's one of opponent monster (example) the dark creator. if he/she use the effect without normal summon, i can't use this card. How if he/she normal summon first and then use the effect or he/she use the effect first and then normal summon? If there's opponent effect monster card that exist for more than one turn, and then my opponent normal summon another monster, can i use this card, if the effect flip, trigger, continuous, ignition? help. really confused bout this card, thx
