Depends on your play style :3 if you want a hyper nuke team then get 2 legend stone for Avant and Sirius (for trials and PVE only), if you want a team for Arena then go for Avant and Mifune, if you want an all around balance team then go for OE Sirius then head for Krantz later. In short, OE Sirius is a must have because of his Enhancement skills and his SBB (The spark damage combined with Avant is beyond imaginable). I would go for Sirius first then get Krantz second, Avant and Mifune can wait because those 2 are valid nukers so if i evolve then but cannot upgrade their BB level then i can't use them at all (because they have the most damage potential in their UBB and SBB, not to mention the spark damage boost)
