The most important part of the Wayfinder for me is the milling. In that department, the Analyst is just as efficient (since one of the cards from the Satyr goes to hand).To be honest, I think this is significantly worse than Satyr Wayfinder. Being able to "draw" a land immediately frees up the creature to enter combat without needing to worry about dying– full value will already have been attained. Plus, Wayfinder mills an extra card, which is really useful for graveyard decks.
So is the body + ability better than a land in hand?
Most of my GY and land decks are on the slow side, trying to recur stuff and gain incremental value. In that context the 1/3 body is a pretty big upgrade over the 1/1 which has minimal value. You do make a good point about risking the Analyst in combat, but it’s just a 2 drop and you’ve gained some value by milling presumably.
Splendid Reclamation is a great GY payoff, but it’s tough to dedicate a slot to it in some cubes. The Analyst does that for the same mana cost! That is an insane ceiling for a 2 drop whose floor is very good too.
I am a big believer that if you want cool things to happen in cube, you have to sow the cards that can let it happen. Here, the cost is so low, that it’s a no brainer for me. If you like more predictable outcomes I can respect the Wayfinder.
I’m not sure that I want both creatures, but in case I do, this is a solid suggestion.I think if you do want to cut something for this card, another piece for the lands deck along the lines of Explore is probably a better pick.
