Favorable Winds is in Ixalan. Just curious, how many similar effects do you figure are in standard all at once? Also, how effecient are you looking to get? +1/+1 global effect for a mere 2 mana is pretty darn good. Nothing else in blue/black standard right now pumps flyers.
Fell Flagship pumps pirates.
Vanquisher's Banner (CMC 5) pumps all creatures of a chosen type; plus it draws you a card.
