The awesomeness of Deep Sea Diva

Let's say we run 3 Deep Sea Diva, 1 Atlantean Marksman and 1 Atlantean Dragoons in our deck

Summon Diva equals:

*Herald of Pure Light:  Recycle basically everything you want to recycle with minimal cost. Getting back BLS/Dark Armed Dragon/Master Hyperion/... while returning a useless card to your deck? Too good

*Trishula: Marksman attacks calling out Dragoons, make Trishula. 1 card Trishula without required setup? Too awesome

*Daigusto Phoenix: 3000 damage

*Gachi Gachi: Classic wall

*Armor Kappa (in case you run Heavy Infantry): Clear 1 face-up card, even Dimensional Fissure, while gaining 1000 ATK permanently

*Catastor: Classic crusher

I'm wondering why Konami decided to release Trishula but not hit Deep Sea Diva. Because they think people would still main deck Imperial Iron Walls? So retarded
