Otrimi lands was amusing but, as anticipated, awkward as hell. So, it's time for an alternative take: Otrimi hexproof/indestructible. I'm aware that the title misleadingly implies that the archetype is eggs, but I don't care.
Specifically, the key card here is
Elusive Tormentor // Insidious Mist. Find it, flip it, dump every mutate in existence onto it. As a backup, we've got
Thrun, the Last Troll and
Troll Ascetic. They die to
Wrath of God, and require mana up to regen, but at least they can block and don't require as much setup. Also have 1 witches cottage to recur it once if necessary.
Of course, requiring a non-commander creature to start doing anything proactive is pretty limiting, so we're running every tutor imaginable to get this party started.
The rest of the deck is basically just a control deck with some light ramp. Mutates should take care of the rest - mopping up problematic permanents and giving lots of assorted value. Loam engine is in there as well, because honestly I just can't help myself. It's not a crucial part of the deck, but it fills our grave with mutates and lets us hit land drops reliably.
