Can the Necromancer activate his Reanimate familiar at the start of his turn, voluntarily destroy it, spend an action during his turn to create a new Reanimate familiar, and then activate this new Reanimate at the end of his turn?
We had this same question. I say based on the rules and how it talks about "each familiar" that a hero controls that this should be legal. I would like to know this as well.
Well, the only way to voluntarily destroy it would be to attack it (you can't unsummon it). Why you'd want to waste one of your actions doing that is beyond me.
I think the intention behind the rules are clear, your reanimate familiar is your reanimate familiar; regardless of how many times it is killed/summoned it is the same card/ability/creature. However even if your group agrees that the technical wording of this is in question and you want each summoning of the token to be a "new" familiar, I have a technicality for you to keep in mind when playing.
Pg. 17 Familiars (2nd paragraph) "A hero player may activate each familiar his hero controls once during his hero's turn (either before or after resolving ALL of his hero's actions)."
With this in mind you CANNOT [Summon, Activate, Un-summon, Summon, Activate] Once you summon your token, you have spent an action and must wait until your second action is complete to activate him, thereby bypassing the first window of opportunity for you to activate him.
However, if your familiar is already summoned and alive at the start of your turn, you could then [Activate, Unsummon, <Hero Action, Summon>, Activate]. This way, even if the intention is to allow 2 activations , the OL has a chance to bash the skeleton on his turn to prevent it.
Hopefully this helps.
