Tyrant Rally All

Activation - Increases the Attack of all allied Assault cards.

Be warned that when used by an Assault card, it will only benefit other assault cards placed to the RIGHT of the one using it (and the user, of course); ones to the left (that is, Assault cards played earlier) will have already used their attack by the time it activates, and won't benefit from the increase.

This is not an issue for Rally All effects used by other types of cards, since other types of cards will always activate before your Assault cards begin their attack.
