Seam Rip answers the cheap pieces their ramp and landfall plan runs on: Llanowar Elves and Sazh's Chocobo (both mana value 1), plus Meltstrider's Resolve, all for a single white mana. Sunspine Lynx is a 5/4 body that deals damage to each player for each nonbasic land they control (their Escape Tunnels, Fabled Passages and Ba Sing Se). Our own nonbasics take the same damage, so it's not free. It also stops Esper Origins' lifegain, though it turns off our lifelink too. Super-Soldier Serum is too slow against a deck that can out-grind with repeated landfall triggers, and Skateboard's tempo is less valuable than hard disruption here. Keep the low curve and equipment synergies to close the game before their ramp payoffs take over.
Rest in Peace shuts off Enduring Curiosity's recursion and any graveyard synergy they lean on (such as Yuriko counting cards in their graveyard), while exiling their graveyard outright. Get Lost answers Kaito, Bane of Nightmares or Floodpits Drowner. Voice of Victory is the cut here since its mobilize tokens are sacrificed at the end step and its 1/3 body does little against a removal-heavy plan, and Super-Soldier Serum is a slow value card against a deck full of cheap removal (Bitter Triumph, Requiting Hex) that can just kill the aura target. Keep the aggressive equipment core intact to race before Enduring Curiosity and Kaito take over.
Chainsaw's entry damage picks off small creatures like Gene Pollinator or Callous Inspector, and the rev counter growth scales well in a long creature-combat grind. Sunspine Lynx punishes their nonbasic lands (Blooming Marsh, Overgrown Tomb, Stomping Ground, Blazemire Verge) with upfront damage. Multiversal Passage comes out since the extra color flexibility matters less than board presence against their go-wide creature plan, and Skateboard's tempo is outclassed by Chainsaw's removal utility here. Focus on efficient trades and equipment value to outgrind their midrange creatures.
