Im including some ways to convert creatures dying to extra damage: Syr Konrad is a very interesting card for Commander because it deals a point of damage for a wide variety of reasons: when another creature dies (which happens a lot, especially with Korvold around), or whenever a creature is put into a graveyard from anywhere other than the battlefield (such as discarding or milling), or whenever a creature card leaves my graveyard (such as some form of recursion)
