Yes, we have access to Duals and Moxes, some Elves and Mana Birds, Initiates/Priests (outside of Sweden, at least), and a Prism that Ive never seen anyone play, but once you add in Factories, a Strip Mine or four, Maze, Library, youre suddenly running 25+ lands
While there are several other versions of Elspeth I'd probably be keener to put in a Trostani deck, the original Elspeth Tirel at least makes sense
Marchesa, the Black Rose is certainly an excellent card, and Silence has its place in cEDH, but its basically a grouping of sub-par/good cards that players either already have, dont really need, or already had access to for a couple of bucks if they really did want them
They cost no mana to play but a player may play no more than one land per turn, and only during the main phases of their own turn
