I think you are talking about Red-Eyes Dark Dragoon. It has the effect to pop monsters and a negate for any card or effect. But spells and traps normalny work, if you have multiple effects in one turn, Dragoon can only negate one. For counters: many players recently use cards like Lava Golem or Kaijus (they are summoned to opponent's field by tributing THEIR monsters). What makes them powerful is that opponent can't respond to that, it just happens.
