Really? I know that CA isn't even Tier one unless it's a hybrid with Vennu and Safria. Not to mention a lot of people already have a defense for CAs in the first place. It should had dropped to the tier 2 or even 3 by now.
Trust me, I run a CA hybrid deck with Cyber Girls. Most of the time I summon CA Dakini more than I do Cyber Blader (mainly because I have one copy of CB and one Fusion Gate in the deck). But as I can only run 1 MAR with a Dakini in the Deck, I don't have much protection. With Hymn of Light, you gain extra protection. CA by itself ain't meta.
