FAQ / What is the timing of triggered effects? If I play a Ferocious Roar with Wildwood Sower in play, does the Seedling gain the bonus from Ferocious Roar?
Triggeredeffects occur after the resolution of the effect that caused them. In this example, Ferocious Roar’s effect occurs immediately when you play it, giving all of your creatures that are currently in play a bonus. After that, the game checks for any triggered effects waiting to occur, and you put a Seedling into one of your lanes with Wildwood Sower’s ability.
