Need:
$ Yedora, Grave Gardener - Sweeper protection/ramp
Kadena's Silencer - Counter all abilities

Consider:
* Rishkar's Expertise
* Farseek
Destiny Spinner - Uncounterable creatures
Leyline of Anticipation
Reality Shift - Somewhat flavorful removal
Force of Will, other counters - Protect Animar
Rampant Growth
Beastcaller Savant - Hasty ramp, but cannot use to pay unmorph costs
Farhaven Elf - Not enough copies currently
Mana dorks
In the Web of War
Genesis Chamber
Cryptolith Rite
Rhonas's Monument
Pir & Toothy
$$ Equilibrium
$ Tishana, Voice of Thunder - Draw a bunch of cards hopefully

------------

Considered cuts:
Mistfire Weaver - Protect something from targeted removal
Temur War Shaman - Most of my dudes are pretty small, so not sure I want to fight, but at full discount it's good value anyway
Nikya of the Old Ways - I still have a not insignificant amount of non-creature spells
Heroic Intervention -> Do I need to protect my low value creatures or can this be better used elsewhere?
Surrak Dragonclaw - Not directly morph-related, and who's going to counter a morph? Mostly useful to help Animar
Red Signets
Lifecrafter's Bestiary
Temur Ascendancy - Mostly only get haste from this because my dudes are tiny
Skirk Alarmist
Backslide
All Is Dust
Primal Whisperer
Riptide Entrancer
Dwarven Blastminer
Voidmage Prodigy

Cuts:
Ashcloud Phoenix - Very expensive to unmorph
Sagu Mauler - Just a big, dumb dude
Silumgar Spell-Eater - Mana Leak is rarely enough to counter the important stuff
Hystrodon - Quite a lot of mana to draw one card
Ethereal Ambush - Instant speed and potentially two morphs is nice, but it's pretty expensive for possibly only two 2/2
Muraganda Petroglyphs - Doubles the size of morphs, but only as long as they stay face down, and that's not really how I'm planning on winning
Obscuring Aether, Dream Chisel - Can discount morphs if I don't have Animar, but I don't expect Animar to die a lot
Thelonite Hermit - Can make a bunch of chump blockers, but mostly only interesting if I do it repeatedly
Purphoros - Needed in Wort
Primal Surge - My permanents aren't exactly impressive when they come in face-up
Explosive Vegetation - 4 mana to ramp a bit, but can't be discounted
Thought Harvester - This let's me win on the spot with Ancestral Statue combo, but doesn't really do anything otherwise
