The second, while afflicted with the dreaded once per turn clause, is also a great way of building board presence as you shenaniganize elsewhere
If setting up lots of mana to win isnt your thing, Kess, Dissident Mage can simply win you the game on the spot by having Intuition fetch up Thassas Oracle, Demonic Consultation, and Reanimate, and its hardly the only commander with access to these kinds of shenanigans
Assuming you're casting this on your own turn, you'll be the last one to get anything into play
Just about every MTG set has a red sorcery that does one damage to each creature an opponent (or every opponent) controls - with an equipped Ghyrson on the board, that becomes a one-sided board sweeper (indestructible creatures, and creatures with protection from red or blue not withstanding)
If you head over to MTGA to try out Brawl builds after this teaching opportunity, make sure you bring Arena Tutor with you
