Meta feels more aggressive and not as land dependent. So cuts to some Land Destruction Spells for other removal and utility are in order. LD on Turn 2 feels important so Maximizing the 3cmc Land removal is a priority. Mwonvuli Acid-Moss gets removed from the deck because I feel like in this economy, 4 mana will be your top end for land removal. So, my suggestion for this space goes between this and Earth Rift. Both cards are some form of resource advantage, but at this time, I like to maximize the value present in faithless looting and it turns out that you can't cast Mwonvuli Acid-Moss from the grave yard.

Out also goes one copy of Ulamog's Crusher. Adding a few more land and Faithless Looting over the Extra Wild Growths and Tinder wall makes the deck more consistent, but less explosive. 5 mana on board seems the norm over 8 mana. So to start with an Ulamog's Crusher in hand early would be uncastable in the early turns. You could loot it away instead and later on use the 2 copies of Pulse of Murasa to rebuy the creatures that you looted away or ate removal while also lightly hating on burn. An additional firebolt goes mainboard to hate on the early aggressive threats and work with faithless looting.

General artifact and enchantment hate gets traded in for Ancient Grudge and Reverent Silence

With less land removal being needed gives me the sideboard slots for some graveyard hate in the form of relic of progenitus

Firebolt and Serrated arrows get traded into more specialized removal. Flame Slash for the sturdier creatures. Aftershock against go-wide decks, boggles, and Gurmag Angler. And a Fun-Of Dead//Gone to tempo gurmag anglers, mess up spell targets, fog a big single attacking creature or shock a small aggressive creature.
