Reason // Believe lets you cheat a creature directly onto the battlefield from the top of your library — the Believe half is doing the real work, and at five mana with convoke available it's faster than it looks. Reason // Believe is a staple in Kenessos, Priest of Thassa decks specifically because scrying into a high-power creature and then slamming it into play for free is exactly what that engine wants.
Best Commanders
Commanders with the highest synergy
Kenessos, Priest of Thassa
Kenessos, Priest of Thassa triggers off putting high-power creatures into play from the top of your library, so Reason // Believe is a two-card engine on its own — Reason sets up the hit, Believe delivers it and fires the trigger.
Galadriel of Lothlórien
Galadriel of Lothlórien rewards scrying and looking at the top of your library, so Reason // Believe pulls double duty: the Reason half feeds her synergies while Believe converts a stacked topdeck into an immediate board presence.

Reason // Believe is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker, but it's almost exclusively a Commander card in practice. In competitive eternal formats the effect is too slow and too fair — five mana to put one creature into play doesn't compete with what Modern and Legacy are doing by turn three. In Commander it earns its slot in specific topdeck-manipulation strategies, particularly any commander that cares about what sits on top of your library or rewards cheating high-CMC creatures into play. Outside those focused shells, it's a niche role-player rather than a universal include.
