Some suggestions for cuts:

• Ring of Three Wishes way to slow
• Disenchant to many redundant effects
• Canopy Claws better play a removal spell like Path to Exile
• Shackles see above
• Robe of Mirrors replace with board protection instant (see abve comment)
• Dawn's Reflection see comment to Kodama's Reach
• Journey to Nowhere, Oblivion Ring, Pacifism focus more on own strategy that disruption the emeny one. And spot removal should always be an instant
• Angelic Chorus not needed
• Wall of Resistance for maybe Stoic Ephemera
• Gatecreeper Vine for a wall that really ramps you (see comment above).

Hope that helps.

Some upgrade suggestions:

You're playing way to less lands. Go up to at least 38 Lands.

Ramp:

Add more ramp (in sum you should end at around 9-11):

• Arcane Signet
• Vine Trellis
• Sylvan Caryatid
• Sunscape Familiar
• Overgrown Battlement
• Rampant Growth
• Farseek

but cut Kodama's Reach wtih execption of Axebane Guardian the ramp should help you get out Arcades at round 3, if possible.

Protection:

Replace Intervene with a flicker spell for one mana. Same effect but better synergy with commander. For example:

• Ephemerate
• Essence Flux
• Now You See Me ...

Replace Miscalculation with Arcane Denial

Replace Remove Soul with Displace or even better a board protection spell like:

• Your Temple is Under Attack
• Unbreakable Formation
• Make a Stand
• Rootborn Defenses

Replace Seedling Charm with one of the following:

• Ajani's Presence
• Loran's Escape
• Tamiyo's Safekeeping (not exactly a budget option compared to the rest)
• Restoration Magic

Removal:

Replace Solemn Offering with Stroke of Midnight

Add an additonal one-sided massremoval like Slaughter the Strong

Backup for Commander:

Add

• Assault Formation
• High Alert
