Daxos's toughness is equal to your devotion to white. (Each in the mana costs of permanents you control counts toward your devotion to white.)
Whenever another creature you control enters or dies, you gain 1 life.
Daxos is a mono-white lifegain engine: flood the board with creatures so every enter and death triggers ping you life, then convert that life total into a win. He's also a resilient enchantment creature whose toughness scales with your white devotion, making him hard to kill in a heavy-pip board state. You go wide, gain incidental life, and close with lifegain payoffs, token swarms, or life-as-a-resource combos.
Add fast mana and ramp (Sol Ring, Smothering Tithe, Nykthos, Mana Crypt) to outpace mono-white's slow start, then tighten the deck around a compact combo line like Heliod + Walking Ballista or Heliod + Spike Feeder. Include strong card-advantage pieces (Mangara, the Diplomat, Welcoming Vampire, Esper Sentinel) and recursion to recover from board wipes, plus protection like Teferi's Protection and Flawless Maneuver.
