Lastly, I want to talk about one of my personal favorite from childhood, even though the card itself is basically terrible: Warping Wurm
If you have Bruna, the Fading Light or Gisela, the Broken Blade as your commander and meld them, the melded creature is still classed as your commander
The Sagas should only have two different chapter abilities
We definitely want to retain some of the hand and graveyard sculpting, but the hand part will come from slightly more aggressive card draw
Like all combo plays requiring one specific card to work with your commander, you'll need to draw your False Cure or use a Tutor to get it first, and while you're messing about with that, simpler, more powerful decks are already ravaging you
