03/16/2018You can cast Act of Heroism even if the target creature won't be able to block right away, perhaps because you're the attacking player.
03/16/2018Untapping an attacking creature doesn't remove it from combat.
03/16/2018The effects of Act of Heroism are cumulative. If multiples resolve targeting the same creature, that creature can block that many additional creatures this turn.
