No Alternative Art for Tezzeret Master of the Bridge

Why is there an alternative art card for all of the vanguards from War of the Spark except for Tezzeret Master of the Bridge? So now after acquiring all of the regular art and alternative art mythic vanguards that I have, I have to risk getting duplicates of all of those when chancing going after the regular art version of Tezzeret Master of the Bridge from the Vanguard Vault packs at 300 jewels per. I could spend a million jewels and never see that card. That's not okay at all for a game to be designed that way. There needs to be an alternative art card of Tezzeret Master of the Bridge made available from Chasing Flbthp. Haven't seen the Jace or Karn vanguards in Chasing Flbpth in forever as well, just saying.
