Rulings

From the Monarch release notes

An attack action card going into a graveyard from the combat chain is not the same as being destroyed.
If you elect not to use it’s effect on the first Illusionist attack action card you control that is destroyed, you cannot use the effect for the rest of the turn.
The Illusionist attack action card being destroyed does not need to be the one in the current chain link. For example if an illusionist attack action card in a previous chain link was destroyed (I.e by phantasm at a later point due to an instant or reaction) then Phantasmal Footsteps will still trigger.
When you defend with Phantasmal Footsteps and pay it’s defense becomes 1, even if you defend with it an additional time this turn and pay it won’t add any additional .
Phantasmal Footsteps only changes it’s defense to 1, it does not take into account or remove any -1 counters. If Phantasmal Footsteps has a -1 counter on it then its defense becomes 1, it would have 0.
You can defend with an equipment as long as it’s in the equipment zone. If the attacking player closes the chain, Phantasmal Footsteps would return to the equipment zone provided it was not destroyed by defending an attack with 6 or more and thus you would be able to defend again.
Phantasmal Footsteps does not have Battleworn. It will not gain a -1 counter from defending.
Phantasmal Footsteps becoming 1 lasts until end of turn. You do not have to pay again if you defend with it a second time for it to have 1.
You cannot gain action points during your opponent’s turn. (You may still pay the if an illusionist attack action is destroyed, you just would not gain the action point when it resolves)
