Cast Rise of the Dark Realms while your opponents have most of their decks in the graveyard and youll likely win the game soon after
Essentially, we need some counterplay, just like every other strategy has counterplay
Sarulf is best suited for multiplayer games more creatures dying
After taking another look these are cards you'll miss the least IMHO: Rune-scarred Demon (this is a lot of mana for the effect in my experience, and it's better in decks that win via combos), Burning Rune Demon (same as the above, but I like this card a bit more because it's 1 less mana), Patriarch's Bidding (this can be unplayable some games depending on the opponent's deck, and unless I'm missing something you don't have self-mill to make the card better), Kardur Doomscourge (I like this card a lot, but if you need to make space he seems pretty low synergy, also plays poorly with Propaganda effects on an opponent's board), and maybe Rite of Replication (I really love this card, but I feel like it's usually too much mana to 'do the thing', I also feel like you have a decent number of Legendary stuff that can't be copied usefully, I could see this being a pet card)
The scalable power boost puts this little guy over the top as one of the best leaders for red and white Commander decks
