I built a Mythical Beast Endymion deck for master duel, this was a lot of resources out of my pocket and even more tweaking as I get something I could use, I’m still adjusting the deck but I decided to post it for you guys to see.
It’s kinda consistent (but can still brick hard) and very good at beating down opponents who overlook effects, which they usually do (people never notice that master Cerberus can’t be destroyed when 4 or more spell counters are on the field)
Once you get the right setup you can start doing some pretty insane combos, I still make misplays like crazy even though I’ve improved sense I started using the deck.
The first objective is getting electrumite out and astrograph into your extra, the setups astrograph
allows in this particular deck can help take you from there, looping astrograph lets you get the maximum amount of spell counters to work with.
Sadly, people always seem to leave mid combo.
