As soon as he hits the field, he forces a discard from each opponent (a good way to make everyone in Commander hate you, and some love you, depending on the deck they play)
To trim down to a 4-color commander deck might be possible, but that's also a short list of best cards
This is another always-playable, rarely good card
It could be that these are negligible because you can attack someone wholl happily take the hit if you give them back a good card and theyll repay you in kind by reanimating your desired target
Cards like Ruxa, Patient Professor or Jasmine Boreal of the Seven are legendary creatures that benefit you when you build around them with vanilla creatures, but these two arent vanilla commanders themselves
Adapt to your local meta and be aware of the risks Luxior brings to your table
