What is the cheapest way to boost a card? Say for example, I have a Speed UR+, I know i would get more by using only Speeds to boost a Speed, but would it be cheaper, say to fuse 2 Speed Common and Boost using the Uncommon or simply boost with the 2 common? Also what about 2x uncommon fused to rare and then boost or simply boost with both Uncommon?

Thanks
