Bond of Insight (WAR)

Sorcery

Each player mills four cards. Return up to two instant and/or sorcery cards from your graveyard to your hand. Exile Bond of Insight.

Reliable card advantage engine for blue tempo and spellslinger decks. Bond of Insight fills your graveyard while returning two key instants or sorceries to your hand, effectively turning a self-mill into a two-for-one in the right shell. It shines in Pioneer and Modern decks built around flashback, storm, or instant-heavy strategies where the mill is incidental upside rather than a drawback. The four-mana cost is reasonable for the value generated, though it requires a deck specifically built to maximize the graveyard synergy—it's not a generic blue draw spell.
