The result is that abilities that cost mana are generally harder to use than you might expect because so many things are asking for your mana
For 7 mana, over several turns most likely, you get creature tokens whenever one of your modified creatures dies
Over the years its become a much-debated focal point on whether it should be banned or not, whether its healthy or leads to degenerate battlefield states too early in the game
As you progress to putting together your own ideas and building more and more effective decks of your own, one of the tools that will serve you well is the ability to recognize the criteria that makes some cards "always" better than others (so you can pick them)
The 083 and 084 sorters recognized these multiple-digit or multiple-zone punches, sorting them to the error pocket
This allows for shenanigans with any artifact that has built in cost reduction mechanics like Myr Enforcer or Metalwork Colossus, potentially turning a card that costs nothing into a defensive fortress like Darksteel Forge or a deadly finisher like Blightsteel Colossus for hilariously discounted rates
