Alright, let's check these cards.

Blitz: Well, the ability is pretty clever, but it can do overboard if your opponent has a 6-cost card on the field. I think we agree that gaining 6 mana in a turn is pretty powerful. So maybe remove the part where you gain mana from the ability.

Agent 3: Make this a 4-cost. Other than that, good card.

Candlehead: Turn this one into a 3-Cost. Good card.

Creator Godcat & Destroyer Godcat: I think I don't understand the ability. You mean that if you have both cards in your deck, and you play one of them, you can swap them during your turn with no mana cost? That sounds like a pretty good ability. Still, 7-cost is too much for this. I'd make them 5-cost cards.
