Maybe you wasn't listening mate but maybe I wasn't being clear enough. Impulses aint usually turn 2 plays unless you is got a combo you are frantically searching for or really need your anger of the gods.
Impulse is a turn 2 play the same way brainstorm is a turn 1 play.
Play impulse once your plan has started to have legs and you have some extra mana to spend on one of your turns, I know you're gonna we've all put a lot of emphasis on bulking up the 1-2-3 slots at the expense of 4-5-6.
Now [Turn 2
Grisly Salvage -> Turn 3 Tasigur + Removal Spell] is great but thats a special case.
