Complete the Circuit

Strategy & Gameplay

Complete the Circuit is a versatile blue instant from March of the Machine that offers exceptional utility for spellslinger decks across multiple formats. With a mana cost of five generic and one blue, the convoke ability makes this card significantly more castable than its raw mana value suggests, allowing you to tap your creatures to contribute toward the cost in the form of generic or blue mana, which is particularly valuable in creature-heavy strategies. The card's primary value comes from its two powerful effects: granting sorcery spells flash until end of turn allows you to cast traditionally slow spells at instant speed, fundamentally improving your tactical flexibility and responsiveness, while the second ability ensures that your next instant or sorcery spell gets copied twice with the option to redirect targets. This combination makes Complete the Circuit an excellent finisher and tempo tool that can turn a single burn spell, card draw spell, or removal into a devastating play that generates significant card advantage or damage output. Players looking to build control, tempo, or spell-focused strategies in formats like Pioneer, Modern, and Commander will find this card particularly appealing. It slots naturally into izzet (blue-red) and mono-blue decks that emphasize instant and sorcery spells, instant-speed interaction, and creatures with utility abilities. The convoke mechanic means you're not locked out of casting this card even if your mana development stumbles, making it a reliable inclusion in mid-range decks. In Commander, it serves as a powerful role-player that can amplify your spell suite and provide the flash-giving ability to support instant-speed strategies. Whether you're copying a critical removal spell, doubling up on card advantage, or generating extra damage at a crucial moment, Complete the Circuit rewards creative deck construction and timely casting for meaningful tempo and value swings.
