inga and esika rain on your parade (EDH / Commander)

An Inga and Esika budget-ish deck. Expensive cards that I'd like to put in will be added to the sideboard (plus a couple Lesson cards), and various other cards for interesting build ideas in the maybeboard. My main goal is to get a deck under 30 dollars.

$27.27 on TCGPlayer at the time of writing. tbh I'm excited enough about my own cleverness in making this deck under a budget limit that I'm super tempted to just buy the full deck.

Only 9 nonlands in the full deck.

Inga and Esika here works as a combat enabler, and as a value engine for just zapping out a dozen creatures a turn.
Copperhorn Scout gives me a free untap every combat he fights in, letting me potentially double my creature mana.
Tatyova, Benthic Druid gives me free card advantage whenever I put down a land, which I want to be doing consistently anyways.

Primeval Light for the kind of players who use Smothering Tithe or Black market Connections. you know the ones.

Ground Seal to prevent your graveyard from getting exiled. You get value from keeping certain cards in your graveyard in this deck, like Wonder or Brawn. Besides, you can pop your Cankerbloom or Reclamation Sage on it if you really need to get value out of something like Genesis or Deadwood Treefolk.

Vivien, Champion of the Wilds can potentially let me use creatures as combat tricks.
Vizier of the Menagerie, Garruk's Horde and The Reality Chip let me dig through my deck, potentially casting cards I haven't even drawn yet. Using creatures for mana with my commander out would allow me to draw, getting even more value out of the spell. Using the knowledge that those cards give me, already kind of stacks the deck for using Deceiver of Form's ability, so i could potentially turn my board into a bunch of Titanoth Rex to beat someone up.
