Soooooo, if I attack with one of my creatures (tap it to declare attacker) and then before combat damage phase, I activate Slayers' Stronghold to give the creature +2/0, haste and vigilance.. does the creature untap because of it gaining vigilance?
Vigilance only matters at the time you declare attackers. Slayer's Stronghold's ability doesn't say it untaps the creature, so it stays just like it is.
