Honorable mention: Jaxis, the Troublemaker
Jaxis, the Troublemaker has the same feeling as Feldon of the Third Path and both cards are very likely to be found from these decks. Jaxis's ability to copy a creature you control and turning it into a card draw in mono red is fantastic and quite rare.
Jaxis gets the honorable mention for the flexibility providing the command zone a strong, repeatable card draw AND any other possible ETB or what not will definitely make this very interesting commander for mono red players.
The Blitz ability gives Jaxis a great upside to work as a combo card, with the ability to copy an important creature you control with 3 mana only! WotC has clearly given Jaxis the limit to use to copy ability as an offensive ability pushing the commander to more aggressive playstyle.
Similar to Rionya, Fire Dancer I can see Jaxis having a strong combo potential due to having cheap coy effect with Combat Celebrant or any other similar kind of extra combat / extra turn effects.
1. Anhelo, the Painter
Anhelo, the Painter is the main commander from the commander precons for Grixis / Maestros. Anhelo gives casualty 2 for the first instant of sorcery you cast every turn and allows you to copy your spells by sacrifising a creature with power 2 or greater.
There are so many different themes you can go with Anhelo: reanimation decks, magecraft tribals, 2/2 token decks, death-trigger decks, copy tokens, steal spells... The possibilities are endless and therefore it is the #1 deck on this list.
My first idea for Anhelo was a magecraft tribal and there are 10 actually good cards with magecraft from Strixhaven, and adding the usual spellslinger staples like Guttersnipe and Firebrand Archer. Most likely finding the balance between sac fodder and useful instants and sorceries will be the challenge, but it will definitely be a fun and difficult deck to pilot.
2. Kamiz, Obscura Oculus
Kamiz seems like an interesting, saboteur specific commander a massive push in combat. With a single trigger from Kamiz, you can get 3 combat damage triggers to an opponent, and in the worst case 1 trigger. This is great example of an evergreen mechanic being pushed with the commander, and therefore making old, not-so-useful saboteur creatures into haymakers for certain decks with the combination of being unblocked, or having double strike, like Graveblade Marauder or making already strong creatures to game enders like Virtus the Veiled.
Kamiz also seems like a strong ninjutsu-commander, .
3. Henzie "Toolbox" Torre
Today, as I first saw Henzia I knew wanted to build this new, weird, sac and cast jund deck. Giving Blitz for your every CMC<=4 just... sounds crazy! I suspect the new jund deck will be a blitz-tribal, as the cost reduction will be very powerful with cheaper ETB creatures with Blitz already, and giving the big creatures Blitz might just make otherwise not-so-playable creatures the needed push to make them playable.
