Khemba is going to be the better general most of the time, but Raksha is a solid number two choice
However, with limited numbers of essential cards like 004-018-mirabel-madrigal-gift-of-the-family and 004-013-julieta-madrigal-excellent-cook, the deck really isnt a strong choice in terms of overall power
You can compare it to a more recent card like Oildeep Gearhulk
Fast and aggressive threats like Scorch Spitter , Runaway Steam-Kin , and Fervent Champion form its core, while Light Up the Stage maintains the pressure
Fewer fetchlands and shocklands also mean more basic lands for U/W Spirits, which, besides less damage taken, also means its naturally going to be better against Blood Moon, always a problematic card against nonred three-color decks
Personally, I feel that he would be stronger if the second and third modules were swapped, even if we removed the Indestructible counter from this ability
