There are a few removals like Shriekmaw or Karn Liberated, but for the most part they are shut down quite ably
The sacrifice ability occasionally came in handy, guarding against mass removal even though it was never the primary motivating factor, and it was hard for decks running him to justify keeping the necessary mana untapped until very late in the game

In those lists it does suffer more heavily from being a card you rarely want to draw in the late game
Combo Dragons #3 While not necessarily a game-ending combo, Wrathful Red Dragon and red damage-based mass creature removal can potentially generate enough damage you can fling at your opponents life totals to end games with, or at least take down the archenemy
Certainly if you get to lay him and calm the board with just a +2 then you are going to win if they don't have spot removal for him
