I fully support this idea because it may cause people that otherwise would have left to stay in the game and remain active. It would give the player another personal goal in toribash. This is especially important for those that feel like they've nothing left to achieve in the game and also about the 'Beat X and obtain the X Collector Card' maybe it could be more specific then that like, what if one could be 'Beat (Ern or Moop or Imsku) X times in (Tk or erthtk) to earn the (Ern or Moop or Imsku) Collector Card' - you see? That kind of thing. (It wouldn't be wise to make it obtainable by just one win for obvious reasons). But of course there's one major issue with this and that is the fact that the mods can get updated and the original one that was registered with the achievement wouldn't be recognized but that can be resolved all with some work from the devs...? (The people that manage those game assets) I'd say such an interesting suggestion is well worth the work to be implemented.
