I don't understand the point of Manamorphose.
You don't need bad cards like Edge of Autumn and Lava Dart to enable revolt. Fetchlands/Wasteland do it 90% of the time, especially with Wrenn and Six to recycle them and Elvish Reclaimer as a land tutor/sac outlet.
Tarmogoyf is much better than Greenwheel Liberator. But this deck will draw graveyard hate to beat Wrenn lock and weaken Reclaimer, and that incidentally wrecks Goyf too, so maybe it should be 2-3 copies instead of 4.
Hate seems important mainboard to not scoop too many game 1s. Eidolon is strong against most of the format in any Mountain deck trying to race to 0. Easy include. But Magus has anti-synergy with Wastelock, fetchland shenanigans (revolt, Titania, Wrenn), Orcish Lumberjack (fewer Forests and can't fetch them), and Punishing Fire. And is turn 2 Magus on the draw fast enough to matter? Maybe Magus doesn't belong.
In the non-Lumberjack version, Punishing Fire + Grove seems really good. Also why not play
Wild Nacatl and splash a
Savannah, giving you up to 12 powerful 1-drops for the optimal sligh curve? White mana opens up more SB options too.
Spirit Guides seem bad (card disadvantage) unless we're powering out hate pieces like Magus or Eidolon, and is turn 2 Magus on the draw fast enough? Zoo is supposed to eat blue decks by having more cheap threats than they have answers (Wild Nacatl > FoW). If we start generating card disadvantage, it tilts back in favor of the blue deck. Spirit Guides fit better in the Lumberjack ramp version.
Bojuka Bog and
Karakas should be somewhere in the 75, probably in the SB. 1-2
Crop Rotation may be a good idea too, also enabling revolt and filling the yard for Reclaimer, Terravore 2.0 and Wrenn.
