The Eighth Doctor only got a TV film and a later minisode, but he still gets his own MTG card, and it's another powerful one, letting you play a Historic card from your graveyard every turn
Weftstalker Ardent reminds me of Mirkwood Bats: a non-rare thats so clearly powerful in Commander but surrounded by way flashier cards in the same set (think Orcish Bowmasters or The One Ring in Lord of the Rings )
Dolmen Gate says prevent all combat damage that would be dealt to attacking creatures you control. This is a good representation of Karlachs ability to take reduced damage while raging
Having these creatures die and not having anything in the graveyard to reanimate hurts quite a bit, so in the early game, it is sometimes a good idea to try to discard a cheap creature like Evolved Sleeper or Faerie Vandal to Tainted Indulgence or Evangel of Synthesis so we'll have something in our graveyard to reanimate once our Puppeteers and Anointers start hitting the battlefield
Vraska, Betrayal's Sting could even revive it indefinitely, given the correct play tempo
