Giratina exists as an existence in which "Space and Time do not Apply" which is why he can compete with Dialga and Palkia, because while he can not directly control the 4th dimension to his advantage, he is immune to their effects and thus can force the battle into one of sheer physical power.
Example : Dialga uses it's power to age and opponent instantly. Giratina is not affected because of it's role in the trinity.
Example : Palkia uses it's power to banish something to the edge of reality. Giratina is not affected because of it's role in the trinity.
To repat myself : Giratina can do neither of those things itself, rather than being able to ACT on reality, it is neither subject to or in control of space or time. It is simply the counter existence.
With Arceus existing as a life form that is able to effect those rules, but also immune to the rules.
