Bofur, Reliable Guardian // Concerted Care

Concerted Care can protect a key attacker from removal or combat while leaving a later body, but a 1/1 lifelink is minor and two mana limits adoption.

Could be wrong if If targeted removal and artifact synergies are especially prevalent, its adventure card economy could make it a recurring maindeck card.

The two-mana protection mode is credible for creature decks, but Pioneer efficiency makes a delayed 1/1 insufficient compensation for holding up mana.

Could be wrong if A resilient creature or artifact combo shell could value both protection clauses enough to adopt several copies.

Affinity can use artifact protection, but two mana is a large hold-up cost and the eventual 1/1 compares poorly with Modern's efficient threats and answers.

Could be wrong if If a key artifact-creature strategy needs protection specifically from targeted removal and destruction, it could become a niche sideboard tool.

Concerted Care is functional but slow for Legacy; the tiny follow-up creature does not justify a two-mana reactive spell against the format's efficiency.

Could be wrong if A newly prominent artifact or creature combo vulnerable to removal could create a narrow protection role.

Protecting a commander or key artifact while retaining a later creature is useful in matching decks, but the 1/1 body and one-shot effect are replaceable.

Could be wrong if Legendary, artifact, or commander-protection synergies may make the small post-adventure body more relevant than expected.

A two-mana answer to removal or destructive combat that later becomes a lifelink body is solid value, though it is weak without a worthwhile target.

Could be wrong if Unknown speed, removal, and archetypes determine how often holding up two mana is profitable.
