What are the items which have same effect during a battle?

Question

Some items have same effect during a battle.

For example, Mystic Water and Sea Incense have the same effect of increasing Water type moves in a battle.

Please exclude the effects these items have on the move Fling, as well as out-of battle effects (such as Incense effects on breeding).
