Budget Kadena Morph Custom Faceless Menace (EDH / Commander)

Deck Faceless Menace de Commander 2019 that I modified over time. I'm a casual budget player. I don't usually buy cards more that 15$, even if it happens hahaha

To make it short, I'm trying to ramp with green, draw and control with blue and to have some board destroy with black. Put lot of face down creatures, making good block/attacks, using morph to surprise and get advantage. If the board get full of 2/2, I use Biomass Mutation and Overrun. This is, of course, a mana hungry deck. I manage to do something working well, but I feel I need to adjust the mana somehow..

I use counter/bounce spells with blue to protect myself and be well, you know; bluennoying!! (Kadena's Silencer, Willbender, Mischievous Quanar, Vesuvan Shapeshifter and such)).. It allows a bit of board control as well with Ixidron (though risky), Weaver of Lies is a sweet one as well. And Ixidor, Reality Sculptor well.. I feel it's a must have in [blue] morph and manifest decks. I try to gain time and to manage the opponent board with blue.

I use green ramp spells. I wonder if I should keep Nature's Lore though. Lots of double lands to fix mana fast as well of course. I use the Tribute Mage to get mana production/cost reduction artifacts with it, as well as the Strionic Resonator.. (But given there's only 3 of 2CMC artifacts in my deck, I wonder if I should keep it). Thing is that they are really usefull. Maybe more good 2CMC artifact to add in the deck instead..!?.
I'm ramping to put lots of 2/2 face down creatures, turn them face-up and cast big other creatures/n-c spells. Yeah, no shit Sherlock.

I do have a lot of sweet manifests and ''put face down creature 2/2 on the battlefield'' effects. Thieving Amalgame is insane in multiplayer. Scroll of fate is a MUST. I already did a game mana-short because I had it in my opening hand and manage to play with 4 mana all the game. I was lucky, I got good low-cost morph creatures...
Of course, you want Kadena. But Animar is well, you all know it if you looked for morph, insane.

The first time I customized the deck, I didn't quite understand manifest and some of my cards with this effect. I took out Cloudform fast. He went fast back in when I realized how it worked haha. But at this point, I didnt draw it in any game since.. I feel that, as may as it may not a must have, it may have a real inresting impact, especially if I scry a good morph creature under it.

Of course, Black is removal. Bane of the Living and some destroy target, mostly. I feel I may add more (thinking to add In Garruk's Wake) instead of some green cards. I'll see after trying it more.
I do have Regrowth and Treasured Find. With these 2 and the Den Protector, I can get some neat destroyed cards back in hand. I like them, but I wonder at what point they are really useful..

I feel like more mana ramp or mana cost reduction would be useful.
But mostly, I need more stuff to cast my spells in Flash.. I do have Vivien for the creatures, but I need something bigger.
Wilderness Reclamation would be sweet as well, or any other stuff that untaps my parmanent to cast flash spells. I do have the Seedborn Muse though! Maybe add the blue leyline..?!

What do you think?!
Hope you enjoyed if you read all this hahaha
