Kaalia Recommendations/Thoughts

Hi everyone,

Last time I played Magic was probably in 2006 (regular 60 deck magic) and I have only been introduced to EDH this year which has revitalized my old playgroup.

In terms of deck construction, i'm still pretty wonky with conceptualizing for 100 cards and after some research Kaalia seems to be a pretty straight forward deck in terms of win conditions (drop big stuff, deal heavy damage etc.).

I came up with this deck list:

I was wondering if I could get your opinion if i'm spreading myself out to thin with this deck. I have recursion, draw, removal, protection etc. and I can't tell if I should just be focusing or is making a deck diverse enough feasible especially in a singleton format. I've done numerous play tests and it feels like I keep changing the deck after a few play throughs and would appreciate your thoughts and possible recommendations.

Thank you guys!
