Cagnazzo clarified my relic pulling priorities

Thus far I have not cleared Cagnazzo after trying a bunch of different party setups and strategies. I have the trinity and up til now I've had no trouble mastering the Ultimate+ battles. This fight would be easier if I had a curaga-level (h85)medica and/or a relic with high regen. Hoping to get super lucky next weekend with WHM lucky draw, if not then I will probably target a BSB banner that features at least one of those relic types.  

Has Cagnazzo changed your mythril spending plans and if so, how?
