Resource Advantage : Card draw means more resources, and in MTG, resources equate to power
I could list every new card I love - like Alice, Growing Girl, who lends the Support keyword to your other characters and gains four lore when you reach ten strength, or Sisu, Divine Water Dragon, who allows you to draw a new card every time you quest - but in general all of the new cards in Rise of the Floodborn feel like a shift in power and ability
Holding up two mana is a lot, and holding up two of the same color when youll need that colored mana to cast permanents (or maybe not even have enough to do both, thanks to having other colors of lands to run)
If the creature gets removed from the graveyard in response to activating the Unearth ability, the ability will still technically resolve, but the creature wont return to the battlefield
