The plane of Taramir has reached the end of its time. The struggles of the Waning Age have been forgotten, for the sun has set for the final time, leaving the world in darkness. Much knowledge was lost in the Last Dawn, but magic endures in the darkness, wizards and wise men screaming their revelations into night. Hidden away, the University of the Lorekeepers holds its vast treasure-trove of knowledge for no one to read while in the darkness the slow corrosion of Taramir itself unleashes strange, psychic entities into physical reality.

☼Taramir Block☼
Taramir Block consists of three sets: Taramir, Waning Light, and finally Age of Darkness. All three sets feature the new mechanics Salvage and Decay as well as the returning mechanic Cumulative Upkeep. In addition, Waning Light brought Fateseal into the picture. To this, Age of Darkness adds the return of Vanishing.

Salvage: Salvage is an activated ability that can be activated only when the card with salvage is in its owner's graveyard, when he or she could cast a sorcery. Salvaging a card exiles it and has the listed effects. Taramir introduced Salvage while Waning Light added off-color salvage costs and Salvage spells with effects dissimilar to their initial effect from being cast. Age of Darkness introduces Colorless and Nonmana salvage costs.

Decay: Decay is an ability word that causes one or more depletion counters to be added to the permanent with Decay, and causes it to be sacrificed when too many depletion counters have been accumulated.

I think blue has too many walls and not enough threats. For reference, Magic 2015, a large set, has a grand total of one blue defender at common.

I will note green and white also had two common walls each in AoD.

That was easier to forgive because green and white had more and better creatures to attack with. In contrast, blue has only two decent-sized creatures for their cost.
