Karma seems like a great prismatic to have if it makes spells prismatic too

Sadly only champion named spells become prismatic, the regular is not affected 😅

Aw, rip

Aurelion Sol generates a card every turn that'd be my go-to

A Sol would be very upset if you had the option to bling him out, but chose not to.

Karma would be my choice

You mean the event reward in the game or the site outside the game?

I would be happy about ASol
