I actually dont think that General Kreat offers much as a commander, but shell go great in the 99 of decks such as Krenko, Mob Boss or Purphoros, God of the Forge that are already looking to throw massive amounts of tokens onto the battlefield to finish off opponents
Eventually we got Breya, Etherium Shaper, the best Artifact commander ever printed, but still a portion of the community was unsatisfied because Breya has W/B in it and they didn't like that - despite the fact that you can build her with zero White or Black cards because extra color options is bad or something I really don't know
I wish it was one less mana, but a common three mana counterspell with the graveyard clause ain't bad
In some cases, red players might target their own card with Chaos Warp, such as in response to spot removal, and hope they get something good from the library's top
All the things that make Krenko scary are low cost like Marvin, Murderous Mimic or Sting, the Glinting Dagger
A few of our creatures and a few of our abilities require creatures to attack, and I like if I can get those triggers without losing my creature
