What are some budget ritual strategies, and what core cards do I need for ritual archetypes? So, I’ve been researching decks, and I really want to mess with Ritual summoning. 

I was able to trade for an entire Megalith core and Impcantation engine minus Crealtar and the field spell. I plan on also getting Manjus and Preparations of Rites, but...

**Are there any other pieces I need for budget ritual strategies, and also, what other ritual archetypes are budget and fun?**

Any advice/help would be greatly appreciated.
