Weve seen multiple wedge sets with power levels much higher than Shards of Alara , but allied colored three-color have gotten very little support in recent years
If there is a keyword or an ability word or even a word used in the title of multiple cards using this ability, then we (being Wizards) have done our job to help name this ability
As a rule of thumb, Ive found that if the card(s) in question cannot win you the game outright, the answer is usually No. Cards like Insurrection, Finale of Devastation, Rise of the Dark Realms, Armageddon, and Expropriate are cards that often belong to this category, and should be added very sparingly to your deck
Of the black legendaries in the set, I really love Shadowheart, Dark Justiciar, who is an excellent Commander and card in the 99 of decks with big creatures
I like trains, too
