Rain of Riches
Enchantment
When this enchantment enters, create two Treasure tokens.
The first spell you cast each turn that mana from a Treasure was spent to cast has cascade. (When you cast the spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)

Rain of Riches turns every Treasure you make into a cascade trigger, meaning a single token-generating spell can chain into free spells off the top of your library. The catch is the four-mana enchantment investment — in slower treasure-focused shells like Jolene, the Plunder Queen, that cost pays back fast; outside those builds, it's a dead card.
Best Commanders
Commanders with the highest synergy

Jolene, the Plunder Queen
Jolene, the Plunder Queen is the premier home for Rain of Riches because she generates Treasures from both sides of the table, turning opponents' political spending into a cascade engine that fires repeatedly each turn cycle.

Olivia, Opulent Outlaw
Olivia, Opulent Outlaw creates Treasures whenever her Outlaw creatures deal combat damage, so Rain of Riches converts an already-aggressive attack step into a cascade chain that snowballs the board.

Vazi, Keen Negotiator
Vazi, Keen Negotiator dishes out Treasure to opponents as part of its negotiation loop, and Rain of Riches flips that political generosity into free spells every time one of those tokens is cracked.

Vihaan, Goldwaker
Vihaan, Goldwaker animates Treasures into attacking creatures, and Rain of Riches rewards that mass-token output by cascading off each one when they're spent — the engine runs deep when Vihaan is pumping out gold.

Prosper, Tome-Bound
Prosper, Tome-Bound produces a Treasure every time you cast a spell from exile, and Rain of Riches turns those incidental tokens into additional cascades, compounding the card advantage Prosper already generates.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Rain of Riches is legal in Commander, Legacy, Vintage, and Oathbreaker, but it's a Commander card through and through. In Legacy and Vintage, four mana for a symmetry-free enchantment that requires a Treasure subtheme is nowhere near competitive enough to see play. Commander is where Rain of Riches earns its slot — specifically in treasure-dense builds where the cascade triggers stack multiple times per turn and the enchantment's cost is recovered within a round or two. Oathbreaker can support it in the right signature-spell shell, but the format's faster pace makes the four-mana ask harder to justify unless your planeswalker is already flooding the board with tokens.

Pricing data for Rain of Riches isn't currently available, so check Scryfall or TCGPlayer for the current market rate before buying. Given its narrow home in Treasure-focused Commander decks and relatively high inclusion rates in those builds, it tends to hold a modest but stable price — worth picking up when you're sleeving the deck rather than speculating on.
