Council of Terra

Whenever a player draws their second card during
their turn, you draw a card.
Whenever a player casts their second spell during
their turn, you create a 2/2 white Astartes Warrior creature token.
"The Council of Terra was the ancient ruling body
of the Imperium of Man convened by the Emperor of
Mankind to replace the Imperial War Council in the
early 31st Millennium after the Triumph of Ullanor
shortly before the beginning of the Horus Heresy."
