You still must wait until you can legally play an ally (i.e. you are on the losing side) before activating Aklem’s power.
Gib Aklem's power is used during combat, which means a defender must be put forth before the power is used. Any champion other than the defender (or a champion immune to psionics) can be selected as an ally. Gib Aklem's power can be used when in combat with a champion immune to psionics. It is only the "borrowed" champion that must not be immune to psionics.
A champion can only be used once in any battle, so Gib Aklem's power cannot be used on a champion that has already participated in the current battle. Likewise, a champion used as an ally by Gib Aklem cannot later be used as a champion in another round of the same battle.
En francais:
on ne peut prendre un allié que si il peut etre joué (donc si il est entrain de perdre)
on ne peut pas prendre un champion immunisé au spy, mais l'immunité de champion opposant n’empêche pas le pouvoir de fonctionner
un champion utilisé comme allié ne peut plus être utilisé comme champion dans la même bataille (et inversement)
