This actually reminded me of a recent rscience post I saw . <| sep |> ked up anything yet or looking for anything specific ? What do you have to offer ? <| sep |> Depends on the country . We dragons live longer , too . <| sep |> Helped destroy would essentially be if a source you control destroyed it or dealt damage to it and from there it can work within the normal game rules . But that specifically wouldn ' t be this mechanic . The second example I gave was that even if you dealt damage to it , you didn ' t get the bonus if that damage wasn ' t relevant , and that says nothing of the countless other ways you can score an assist the entire point was to encourage people to work with their opponents by casting pump spells on creatures that aren ' t yours , or countering spells that have no effect on you personally . These are things that just can ' t be quantified in the game rules by any stretch . Your suggestion ignores the fun aspects of this mechanic that embrace its silverborder completely , and then goes on to say that without the part that made it silver border , it can fit in black border . I know this isn ' t something that would appeal to everyone , so I understand you not liking it , but I can ' t get behind your stated reasons . Oh , and uncommon matters is a minor theme of the set . It really isn ' t as deep a design space as it first looks , as if it cares about the opponent ' s uncommons at all its just a sideboard hate mechanic like landwalk was , which I have no real interest in fleshing out .
