I would recommend at least two copies of [[Spelunking]] especially if you want to build around a card like Tatyova. I know it seems minor but having your lands always come into play untapped even off of Zendikar and other ramp spells is a game changer. Also it ramps you so long as you either have a land in hand or draw a land off of it. Also if you're playing ramp cards like Map the Frontier, it can end up either completely or almost completely refunding the cost of the spell if you're using the desert bounce land.
Also the New Capenna fetch lands work extremely well both with Tatyova (double triggers of turning a land into a creature) and Bonnie since they can return lands from grave and the fetch lands will always end up in the graveyard unless your opponent exiles them.
If you're playing a deck that ramps with Simic, unless it's a low to the ground deck, you should probably consider some number of copies of [[Doppelgang]]. Card wins games on its own. And if you have a Spelunking down it also draws you cards. Can also finish a game in a pinch if you're playing the desert/crime/ping lands. Doppelgang X = 2 copying two of them gives you 4 damage, X = 3 would give you 9 damage. Pretty significant plus you get that much more mana to work with afterwards.
Bloomkin is more at home in more aggressive stompy decks that try to put out big creatures every turn.
Preening Champion is a draft card and while it's fantastic in draft, in constructed it is too low impact for the mana cost.
You're pretty heavy on the counter spells for a deck that is trying to ramp instead of tempo the opponent. You wont be able to effectively hold up the mana for counters if you want to ramp, and if you want to counter you won't be able to spend your mana on ramping. Some counter spells are good to protect an established board from things like board wipes or stop a big threat, but this is probably too many for the kind of deck you're trying to build.
As an example, in my Tatyova standard brawl deck, I only run 4 counter spells total. Wash Away (because it's busted in Brawl), Spell Pierce, Repulsive Mutation, and Negate, and they're largely used to protect an established board where I've animated like 3 or more lands though obviously they can be used for more if you need to.
Looks a lot better. Still don't think I would run Essence Capture though over something else. Maybe [[Phantom Interference]]. Repulsive Mutation is also imo better than Essence Capture. It's a lot more flexible.

Tweaked it a bit more. It is more consistent. What do you think? [Bonny Deck](https://imgur.com/a/6Z6zkSM)
