The Invaders leadership Team Tactic Card says you 'can' reroll skulls when within 2 of an ally.
If I use Recalibration Matrix while using this leadership, can I decide whether to reroll skulls either in the attack or defense rolls depending on what is most advantageous?
E.g. 1: I am defending we both roll skulls - I decide to reroll my defense skull, but keep the attacker's.
E.g. 2: I am attacking and we both roll skulls - I decide to reroll my attack skulls, but keep the defender's.
