Sightless Brawler

A 3/2 for two mana in white is a genuinely aggressive body, and the "can't attack alone" clause is the leash that keeps it from being a lone fast clock. The card wants company on the board before it can swing, which folds white's usual go-wide instinct directly into the front-side creature. Where the design turns clever is bestow. Cast for its bestow cost as an Aura, it hands its host +3/+2 and passes along that same "can't attack alone" restriction, so the enchanted creature inherits the very constraint the base card was built around. That is the unusual move: most bestow creatures simply graft stats onto a host, but this one transfers a behavioral limitation alongside the buff, making the restriction a property of the body rather than only a tax on the base creature. The tidy part is that it is the same clause twice, appearing whether the card is a creature or an Aura. And because bestow means the card becomes a creature again the moment it stops being attached, killing the host does not erase your investment: the buff is gone from the dead creature, but the Aura falls off and stands back up as a 3/2 in its own right. The result is a threat that survives its host by reverting, not by lingering as a floating buff, which is exactly the resilience bestow was designed to sell.
