Dialga's new ability: Temporal Shift
Trick room is in effect any time dialga is in battle
("primal" dialga will have very low speed)

Palkia's ability :Spacial shift
Trick room but for accuracy and evasion. Having lowered evasion makes you harder to hit, low accuracy moves are more likely to hit, never miss moves always fail.

Giratina's ability "dimensional shift"
While giratina is in battle, type effectiveness and resistances are reversed.
