Union of the Third Path gains you life equal to the damage dealt to a creature you control this turn, then draws a card — solid lifegain-triggered payoff stapled onto cantrip efficiency. The Archimandrite decks run it in over half their lists because it slots directly into the gain-life-draw-cards engine the commander is built around.

The Archimandrite
The Archimandrite rewards every lifegain event with card draw, so Union of the Third Path — which both gains life and replaces itself — does double duty in one mana-efficient package.

Will, Scion of Peace
Will, Scion of Peace reduces spell costs based on life gained, and Union of the Third Path generates a burst of life in combat while cantripping, which keeps the cost-reduction engine ticking every time a creature trades or eats a removal spell.

Hope Estheim
Hope Estheim cares about gaining life to push damage through, and Union of the Third Path threads naturally into that loop by converting combat damage into life while keeping your hand stocked.

Bre of Clan Stoutarm
Bre of Clan Stoutarm leans on lifegain to accumulate value over a long game, and Union of the Third Path provides a cheap, cantripping lifegain trigger that keeps Bre's engine fed without eating a meaningful card slot.

In Commander, Union of the Third Path is a cheap, reactive spell that fits any white deck with a lifegain theme — the cantrip rider means it never purely costs you a card, and in dedicated lifegain shells it actively generates advantage. In Pauper, the combination of instant speed, lifegain, and card draw on a common is genuinely useful in reactive white strategies, though it competes with similar effects at the same price point. In Modern and Pioneer, Union of the Third Path is too narrow for non-tribal, non-lifegain shells, but it shows up in fringe Soul Sisters-style lists where the lifegain trigger count matters. Legacy and Vintage have far more efficient options, so Union of the Third Path doesn't register there outside of very casual or budget builds.
