I would be careful with what you define as "card draw". Have a think about whether after casting it, you've gone up or down on how many cards you have left to be able to cast. Top deck manipulation is more on the card selection side, which is fine for the plan of putting dinosaurs on top for Gishath.

I would also separate your protection spells from your buff spells, since it's useful to know how much protection you have access to.

I would probably take out Temur Battle Rage as another card to cut for a land. Multiple sources of Double Strike are redundant, and this is probably the least useful one, since you can't set it up on board before you resolve Gishath unlike the others.

Also three green pips for Llanowar Tribe seems unlikely to hit reliably. This is one I would cut for a land.

Also I just thought about Hulking Raptor and Regal Behemoth which are dinosaurs that can help ramp out Gishath that you might like. Commander's Sphere and Chromatic Lantern are a tad on the slower side and could be replaced by these.

This deck is quite the mix, the cards in here that are good are REALLY GOOD like Sylvan Library, Arid Mesa, True Conviction and Etali, Primal Conqueror  ^Flip

But the cards that aren't are complete rubbish, like Manalith, Mirri's Guile and Gigantosaurus (The green mana pips are hard to get reliably in three color and 10/10 with no evasion is rarely helpful in this deck)

And then there are some cards that are fine, but really don't belong in this deck, like Rancor and Almost Perfect

I would also recommend using tags to separate card functions, like your lands, ramp, dino, damage multipliers, card draw, and removal. This will make it easier to see what your deck is lacking. Use the # character in your card editor to tag cards ("# Ramp" for example)

You only have 30 lands, so I would try to get this to 36/38 rather than more ramp spells. The best budget ones you're missing are Sungrass Prairie, Mossfire Valley, Sunscorched Divide, Clifftop Retreat, Rootbound Crag, Sunpetal Grove, Rockfall Vale, Overgrown Farmland, Fortified Village, Game Trail, Fire-Lit Thicket and Furycalm Snarl. There are plenty more I may have missed too.

I think you should try adding a few ways to accrue card advantage, like Rishkar's Expertise, Season of Gathering, Secret Rendezvous, Inspired Tinkering, and Escape to the Wilds. These will help you find more cards once you're running out.

Majestic Genesis is also a cheeky card you might like...

Also, there's now another strictly better Unsummon with Into the Flood Maw

Also, may I share with you Cryptic Command and Dismiss as better versions of Bone to Ash, or Exclude for one mana cheaper if you're only expecting to play against creature decks.

I know it's a non-format deck, but I'm finding it funny that there's 4x Sol Rings, since there's no format (to my knowledge) where more than one Sol Ring is legal.

GAMEBOY1234 I do agree, unfortunately there aren't that many instant speed theft cards in the game, but we don't need that many, since most of the cards in the deck give us a ton of ramp and card draw in order to find those cards. It can win purely on accruing more value than our opponents and controlling the board while the Komas beat our opponents down, like a tempo deck.

The deck is more about being able to keep up 7+ mana at all times, so we can wait before we spend it all on either our control spells or card advantage.
