When is the power of the minion checked to see if it's small enough to summon to any site?
You check at the time of casting, before the minion enters the realm. This means that you can summon a Vengeful Heir to any site, even if it enters the realm as a minion which would be too large to work with Spore Sprouts normally, for example.
