## Description

Rousing Refrain is a distinctive sorcery card from the 2021 Magic Online Promos set, identified by catalog number 90110. Designed for the red mana color identity, this card offers a unique strategic advantage through its Suspend ability. Instead of paying the full mana cost of {3}{R}{R} immediately, players may exile the card from their hand with three time counters by paying {1}{R}. During each of your upkeeps, a counter is removed, and when the final counter is gone, you may cast the spell for free.

Once cast, Rousing Refrain provides a significant mana boost by adding {R} for every card in a target opponent's hand. This scaling effect makes the card particularly potent in matchups where the opponent maintains a large hand size. A key rule interaction ensures that this generated mana remains available until the end of the turn, preventing the typical loss of mana between phases. This permanence allows for flexible spell casting during the same turn the sorcery resolves.

For Magic: The Gathering collectors, this promotional release represents a notable piece of digital-only history. Collectors often seek out these promo cards to complete their Magic Online Promos set or to appreciate the unique mechanics that define digital exclusives. The Suspend mechanic adds a layer of strategic depth, rewarding players for planning their turns and managing resources effectively.

Whether you are building a collection of rare promos or looking for powerful cards with unique rules interactions, Rousing Refrain stands out in the 2021 release. Its ability to generate variable mana and cast for free makes it a fascinating subject for both gameplay analysis and collection building. The card remains a testament to the creative design possibilities within the Magic Online ecosystem, offering collectors a tangible piece of the game's evolving landscape.
