If you get the DNA Splicers and fuse a traded Zekrom & Kyurem will it work?
No... You need to beat ghetsis and the champion to catch kyurem.. It will then drop DNA splicers. Then, When you get the splicers yoy can fuse any traded zekrom/reshiram with kyurem
yes it should.
You can't fuse the too Pokemon without the Dna split thing that drop's
