Horn of Plenty draws a card for every opponent who plays a land, turning a four-mana artifact into a passive engine that scales directly with table size. In a four-player pod you're getting three triggers per round; the cost is trivially paid by the card advantage it generates.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

| oathbreaker | legal |
Commander is the only format where Horn of Plenty is meaningfully playable — three opponents taking land drops each turn means you're drawing roughly three extra cards per round for four mana, a rate that pays for itself within a single circuit of the table. In Legacy and Vintage it's technically legal but sees no play; two-player games cut the trigger count in half, and those formats are too fast for a do-nothing four-mana artifact to matter. Oathbreaker is the one other format where you might slot it, though the smaller table caps your upside. Treat Horn of Plenty as a Commander-only card.

Price Context
Current price
$0.66 bulk tier
At $0.66, Horn of Plenty is genuine bulk — low enough that the decision is purely about whether it earns its slot, not whether it costs too much. The price is stable; it's not trending in any direction, and there's no obvious reprint risk that would crater it further.
