Here’s the rundown:

Cats

Savannah Lions was the last of the Cat tribe.

Commander 2013

Toxic Deluge was not only the last Commander 2013 card to fall, but the last card from any of the Commander sets to lose out.

Kaladesh

The last large expansion to be included in the Magic Bracket, Kaladesh, is now out. The last survivor was Chandra, Torch of Defiance.

Oath of the Gatewatch

Standard banned list bad boy Reflector Mage was the last holdout here.

Scourge

Recent Dominaria reprint Goblin Warchief was the last card from Scourge, and the set is now extinct. Warchief was also the last Warrior, the largest creature type to die out thus far.
