Since you're in 5-colors, it might be wise to run Exotic Orchard (often you get 4 or 5 colors on this land), Cascading Cataracts (for General Tazri's ability) and Battlefield Forge. // Also, Arcane Sanctum, Crumbling Necropolis, Savage Lands, Seaside Citadel and Murmuring Bosk (fetchable Forest) should replace the non-gate taplands: Bloodfell Caves, Dismal Backwater, Swiftwater Cliffs, Tranquil Cove and Wind-Scarred Crag. // You don't need to dedicate 10 guildgates to Circuitous Route, you just need 5 or 6 to have wide variety of options to fetch. Since this deck is heavy on green and white, you can take out the guildgates that don't generate green or white (Dimir Guildgate, Rakdos Guildgate, Izzet Guildgate) for Vivid Meadow, Vivid Grove and Vivid Crag, because these can give you all 5 colors. // It is better not to run spells that cost double mana of a splash color, like Diabolic Tutor (it might be hard to cast it when you want it).

eliakimras Thank you so much for the suggestions, I will add some of these cards for sure!

Exotic and Cascading cost more than 1 dólar, here we are talking low my friend rs

I really like the suggestion of the tri-lands, I remmenber they being more expensive, maybe the price dropped or was only here in my country, thanks.

I totally aggre with the Guildgate statement.

About the double mana, there are very specific spells like Twilight's Call, Diabolic Tutor and Rally the Ancestors but I'll see what I can do about Harmonize even this card don't cause me trouble to cast. Any suggestions about the double collored costs?

Harmonize is fine, since green is one of the main colors of the deck. Rally the Ancestors and Twilight's Call cost a lot of mana, so it's not hard to have double white or double black in the 6+ mana you paid for them.

But you have no rush to cast these cards, these are the ones you cast afters many board wipes in the 20th turn. No mana issues.

This list looks casual, so Painful Truths and Urban Evolution might find a home here. If you need more draw power, Concentrate and Tidings are there for you. // I would take out Gruul Signet and Simic Signet for Fellwar Stone (4-5 color mana rock) and Commander's Sphere (can replace itself in the late game). // You may take a look at Golgari Charm, Abzan Charm, Bant Charm, Naya Charm and Boros Charm. Charms can be really versatile, while being cheap (mana- and money-wise).
