Green almost never touches the Ring, which is the first thing worth noticing about this 4/4: it is one of the few doorways the color has into a mechanic that otherwise lives in black. The catch is that the doorway opens exactly once. The landfall trigger checks that you don't control a Ring-bearer before it tempts you, and the rules for the Ring tempting you force you to name a Ring-bearer on that very first temptation if you have any creature at all. Name one and the condition is spent: every land you drop afterward sees a Ring-bearer already on the battlefield and does nothing. The repeatable-looking landfall wording is a feint, then. What you actually have is a single guaranteed step onto the Ring's ladder, delivered on the first land you can play alongside it, and it fires again only if your Ring-bearer dies or leaves and the slate resets. That reframes the card entirely. Its real job is access, not acceleration: the landfall line hands a green deck the opening rung of the Ring's escalating rewards, then you climb the rest through other means. The plain body is honest about that limitation. A 4/4 for four asks nothing of the rest of your deck and gives the one-shot trigger a durable place to sit, which is exactly what a card whose keyword pays out once wants: a fair beater that keeps earning its slot long after the temptation has spent itself.
