Since artifacts have to re-activate before each phase, should there not be a time period where the battle phase exists before the attacker is presented. and if that is the case then....
1. Can I Use Gates of Hell to put a blocker in battle before the attacker is presented.
2. I would think that Choose the attacker abilities are similar to choose the blocker, in that if they happen as a result of an enhancement in battle, then they can be interrupted, but if I present a blocker (via gates of hell) and then play a choose the attacker ability, could that be interrupted as well?
Just trying to break the game (a little bit)
