Just a quick question
If perhaps I cast a Collective on my previous turn, and two turns after, I put a creature (let's say a 3/3 Centaur Token), does that creature get the +3/+3 also?
{Collective Blessing}
Yes, it will be affected by {Collective Blessing} and become a 6/6 creature.
This is similar to how elementals created by {Master of Waves} stay alive after entering play.
Thanks Sardok! From now on I'll try to put two copies of Collective instead of one.
