its kinda crap though. 4 mana and it etb's tapped. there's so much more i'd rather be doing with 4 mana than locking myself up for a turn. if this becomes the standard mana rock in commander precons they should just not bother printing them any more, almost any other rock is better. don't get caught up in the 2 mana of any colors part. its slooowwwww.
I feel like this one falls short, unfortunately. Sisay's Ring only taps for colorless, but enters the battlefield untapped, which means it's more likely to have an immediate board impact. That said it also barely sees play in EDH, and I don't expect we'll see Firemind's Vessel showing up very frequently either.
Tapping for two different mana specifically is flavorful, but could also be somewhat of a hindrance for the mono-white or mono-red decks this might otherwise see play in.

That's why Gilded Lotus exists.
