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.
Odric, Lunarch MarshalutilityBudget$0.51Gives your creatures a shared combat-ability suite if any one of them has it, closely matching Concerted Effort's team-wide keyword sharing. It functions as a stronger, creature-based payoff for keyword soup decks.
Shared AnimosityfinisherBudget$1.47A white go-wide combat payoff that rewards attacking with multiple creatures, similar to Concerted Effort's board-wide combat enhancement. It doesn't share keywords, but it fills the same anthem-style finisher role for creature swarms.
Cathars' Crusadeutility$4.97Another powerful white enchantment that scales your whole board over time and turns small creatures into a lethal army. It is not keyword-sharing, but it serves as a comparable enchantment-based team booster.
Anointed Processionutility$59.47Like Concerted Effort, it is a white enchantment that supercharges token-heavy strategies and wide boards. It doesn't grant abilities, but it serves the same role of amplifying your army as a passive engine.
True Convictionutility$5.52A white enchantment that grants a global combat ability package, giving your team double strike and lifelink. It parallels Concerted Effort's team-wide keyword distribution by improving combat outcomes for the whole board.
Akroma's Memorialutility$28.83This artifact gives your creatures a large suite of keywords, overlapping heavily with Concerted Effort's keyword-sharing theme. It is more expensive, but it is one of the closest all-in battlefield enhancers.
Cover of Darknessutility$13.89A tribal enchantment that grants a shared evasion keyword to your creatures, similar in spirit to Concerted Effort's ability propagation. It is narrower, but it occupies the same role of team-wide combat enhancement.
