You can find Metal Tyrannomon at Access Glacier.Or you can match 2 lv.60 digi's to get the Savers Digi-egg which has either SNGreymon, MRGaogamon, Ravemon, or Rosemon. To get METyrannomon get Botamon or Black Agumon, get Black Agumon to Lv.21 with 100ATK and 1000 Dark Exp, and digivolve into DKTyrannomon. Then get DKTyrannomon to Lv.34 with 5400 Machine Exp. to get Metal Tyrannomon. WAIT... Don't you just have to DNA Digivolve a Darkdramon and a Shine Greymon?
