Due to their heavy dependence on "Hole" Trap Cards, en masse Spell/Trap removal will easily bump off these Decks. Similarly "Royal Decree", "Jinzo", "Jinzo - Lord", "Forced Ceasefire", "Dark Simorgh" and similar "anti-trap" cards can severely hinder the Deck unless you control a face-up "Traptrix Atrax", who prevents the activation AND effects of your Trap Cards from being negated. Also, any Decks that running "Forbidden Lance" (or Decks that runs any "unaffected by trap" monsters such as "Troposphere") can evade their Traps easily and still destroy their monsters, making them quite a nuisance.
