At the beginning of each upkeep, creatures you control gain flying until end of turn if a creature you control has flying. The same is true for fear, first strike, double strike, landwalk, protection, trample, and vigilance.
Archangel of Tithesutility$7.67While not a tribe-wide keyword copier, it plays a similar white board-shaping role by making combat awkward and rewarding you with a strong defensive posture.
Akroma's Memorialutility$28.83This is one of the closest functional equivalents, granting your team a large suite of keywords including flying, first strike, vigilance, trample, and protection.
Cathars' Crusadeutility$4.97Like Concerted Effort, it is a white enchantment that scales your whole creature team over time, though via counters instead of keywords.
Eldrazi Monumentfinisher$7.40It gives your board flying and protection while also serving as a powerful finisher for go-wide white decks.
Glorious AnthemutilityBudget$0.45A simpler budget-friendly white enchantment that boosts your whole team, serving a similar anthem-style support role.
Shared TriumphutilityBudget$3.30A tribal anthem that supports a creature-heavy deck in the same broad team-buff space, though it depends on creature type.
Angel of Jubilationutility$10.19It provides a strong white board-wide combat/stat boost style payoff for creature decks and fits the same color identity.
True Convictionfinisher$5.52This grants your whole team double strike and lifelink, overlapping with Concerted Effort's combat keyword amplification plan.
