The Final Fantasy crossover sets also introduced several strong legendary knight creatures, many of which make great commanders
Now, the fact that it includes the Creatures in your graveyard could be problematic
(Chuckle as your opponents try to cast Fog in 2019 when you have eight maindeck ways to incidentally counter it.) Bonecrusher Giant, Wild Slash, Lightning Strike, and Wizards Lightning offer a ton of reach for red aggro decks, and allow you to maintain pressure while cheaply removing opponents threats
Notably, Conflagrate is especially useful in more aggressive builds where you can fire its damage directly at your opponent for lethal points of damage seemingly out of nowhere
Venser also makes random other cards way stronger, like Nasty End sacrifice The Hollow to draw 3 cards for 2 mana, Vat of Rebirth gets loaded with oil as The Hollow dies, or Ringsight to give Venser skulk so we can bypass blockers while tutoring up a card
Rigo, Streetwise Mentor itself gives you a card, and its flexible enough that you can either focus on the attack triggers and saboteur effects (Delney, Streetwise Lookout and Enduring Curiosity, for example), or you can try to overwhelm your opponents with sheer numbers in a token build
