Ritua Chain's Normal Summon ability can be an instant Manju at any time. However, the drawback to this is there's a chance that you won't get a Ritual Spell Card or a Ritual Monster.
Anyway, 1800 ATK monster? Pretty decent ATK I'd say.
For case 1, the Normal Summon ability can bring you this:
Divine Grace - Northwemko
Call of the Haunted
Obviously, one of them is a Ritual Monster. So, you add Divine Grace - Northwemko to your Hand and Call of the Haunted and Dark Bribe goes back to your Deck in any order.
For case 2, the Normal Summon ability can bring you this:
Ritual of Grace
Obviously, one of them is a Ritual Spell Card. So, you add Ritual of Grace to your Hand and rearrange Torrential Tribute and Mirror Force for your draws.
For case 3, the Normal Summon ability can bring you this:
Obviously, you get nothing added to your Hand, but you can rearrange the three cards to whatever you desire.
