Against Mono-Red Sligh's fast clock of burn and aggressive creatures, extra Wall of Roots gives you a 0/5 blocker that also ramps mana, buying crucial time. Wellwisher gains life for each Elf on the battlefield, which can meaningfully offset their burn-based race once your board is developed. Anger, Squee, and Skyshroud Poacher don't impact the race enough to justify their slots, so they're cut for more resilient, defensive bodies. Keep your full mana engine online so you can deploy Deranged Hermit or Natural Order targets to stabilize before their burn adds up.
