Unfun Inalla Combo (might need more interaction)

[subscrublordMTG]

This deck's main focus is a decidedly solidary strategy, attempting to assemble one of the following combos:
1. Dualcaster Mage + Twinflame
2. Dualcaster Mage + Ghostly Flicker
3. Timestream Navigator + Thassa, Deep Dwelling
4. Timestream Navigator + Fable of the Mirror-Breaker
5. Wanderwine Prophets + Damage opponent + 3 open mana
6. Deadeye Navigator + Peregrine Drake + Almost any ETB
7. Thassa's Oracle + Deckout

There are more than this that I found playtesting, but I can no longer remember.  However, looking at decklists and suggestions, It's likely that I'll need to move some slots over for much more interaction.

Here are my current ideas to switch out (in order of most to least likely):
Docent of Perfection
Mystic Archaeologist
Spiteful Banditry
Electrodominance
Archmage Emeritus
Apprentice Necromancer

My first swap would be to get a Mana Drain in, hopefully I'll pull one from OTJ.  Feel free to let me know what you think can/should be swapped out for more interaction.  Suggestions for interaction that have at least 2 of the following are ideal (in relative order of importance):
1. Good early (2-4 mana)
2. Helps to find combo pieces
3. Ramps
4. Is an instant or Sorcery
5. Card advantage engine

I'd start by dropping some lands. 41 is a lot and you could use more ramp.

Of the cards you mentioned I'd cut Mystic Archaeologist first. It's only useful if you can assemble Deadeye Navigator + Peregrine Drake.

I can see dropping a little land for some ramp.  I'll try that out.  I know for sure that the same reason this deck needs ramp, it desperately needs to hit its land drops, and I thought there was enough draw/selection to allow for more lands.

I'll probably cut Mystic for some interaction.  The reason I initially put it in there is because it's nice to have a repeatable activated card draw ability while holding up interaction, but I can feel it's not performing well enough.

What are some effective ways to improve land consistency and ramp in this deck while still maintaining a good balance of card draw and interaction geometry dash online?

What are some effective ways to improve land consistency and ramp in this deck while still maintaining a good balance of card draw and interaction geometry dash online?

I try to stick to these numbers, but there are lots of decks that go outside these ranges.

12 to 18 ramp
10 to 12 card draw
5 to 7 creature removal
5 to 7 artifact removal

When in doubt, adding more card draw is rarely a bad thing. Card draw can get you into all of these other things.

Spellseeker is a one-card combo with Inalla.
You cast Spellseeker, you stack its trigger on top and tutor for Culling the Weak, you cast Culling the Weak, then you resolve Inalla's trigger to copy Spellseeker, you tutor for Unearth, you cast Unearth to reanimate Spellseeker...
From there I believe you can go many paths to the win.
You already have Spellseeker, you're already on a combo build, you plain to add some high-power cards like Mana Drain...
You should definitely take into account such kind of combo lines.
