If you have 6 Arceus in play and each of them is a different type, search your deck for up to 6 basic Energy cards. Attach each of those Energy cards to a different Pokemon you have in play. Shuffle your deck afterward.

Sky Spear

Choose 1 of your opponent's Pokemon. This attack does 80 damage to that Pokemon. (Don't apply Weakness and Resistance for Benched Pokemon.) Remove all Energy cards attached to Arceus and put them in the Lost Zone.
