Path to the World Tree

The first line is a plain basic-land tutor that adds to your hand instead of your board: it fixes colors rather than ramping, and it fetches whatever basic your manabase is still missing. That distinction matters, because everything the enchantment truly wants lives on its second line, and that line demands one mana of every color to fire. The reward for assembling all five is a scattershot payoff resolved at once: draw two, gain two life, drain an opponent for two, deal two to up to one creature, and leave a 2/2 Bear behind. No single piece is large. The design pays you in breadth, not force, and that modesty is what keeps the button fair despite everything it does. A green shell can bend toward a WUBRG cost it may never reach, and the enchantment shoulders part of that setup itself, priming the exact color it needs to eventually cash the ability. Read as raw efficiency, it looks like a stack of twos stapled together; read as a milestone, it is what you collect once every color comes online and the board has already tilted your way. The greed is not free: you earn the five colors first, then receive a small helping of everything the instant the rainbow is complete.
