Double strike and vigilance is a solid combo, and obviously you want to be buffing this up which also fits
For example, Chaos Confetti, a card that you have to rip into pieces and throw from five feet, would obviously have to be reworked in the digital space to add fairness
Also, without the restriction of specific colors, they can sometimes be easier to cast than cheaper creatures with more restrictive costs
Commander products have repeatedly introduced relevant new Constructed and Cube-relevant cards (and only True-Name Nemesis looked really awkward in a Commander release)
This is particularly powerful because it is difficult to interact with and can seize games even from positions where a player is far behind (indeed, it can sometimes be actually easier to win from bad positions, as boards like multiple Unholy Annex es or an Abhorrent Oculus turn to your opponent's disadvantage against Excruciator)
