Guardian of the Great Conduit is a five-mana 4/5 with reach and the ability to tap for green mana — a body that doubles as a late-game ramp piece. The effect is real but slow; you're paying five for a creature that replaces itself in mana only when tapped, which means it earns its slot in decks that want big green bodies, not in decks that want efficient ramp.

| Format | Verdict |

Guardian of the Great Conduit is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker, but competitive non-rotating formats won't touch it — five mana for a 4/5 with reach and a tap ability is nowhere near the efficiency bar those formats demand. In Commander, it occupies the narrow space of a reach blocker that also generates mana, which is a fine role in a Forests-matter or creature-heavy green shell that needs both defensive presence and late-game mana fixing. Guardian of the Great Conduit is most at home in a slow, stompy Commander deck where the five-mana slot isn't contested by more impactful ramp or threat cards.

Price Context
Current price
$0.06 bulk tier
At $0.06, Guardian of the Great Conduit is pure bulk — you're paying for cardboard, not the effect. At this price tier there's no financial risk in picking one up, but don't expect the price to move; niche five-drops with marginal competitive applications stay in the bulk bin.
