with ascendancy on the field I attack with two creatures. Then I cast a spell that triggers ascendancy. I can untap my creatures ? Will they still be attacking ?
Untapping a creature doesn't remove them from combat and doesn't prevent any damage they would deal or take. This is also relevant for things like {Maze of Ith}, which does prevent the damage, but it's still an attacking creature.
Wow. I played a token deck with goblins. He also used stoke the flames for convoke.
Jeskai Tokens. I have a list somewhere, it's pretty dangerous.
