Notes & Combos
This deck isn't very good and I'm not very familiar with it but it was decent enough for this event.
Main deck ratios can be arranged a little bit, as I only play 1 Showdown and 1 of each high level S-Force outside of the mandatory 3 Gravitino. I kept 1 Dog Tag in but it rarely came up for me.
I opted for a Ptolemaeus package with Constellar Diamond and Pleiades in the extra, expecting to face a few Orcust decks. I didn't face any but it still came up once or twice. Other cards like Exciton, Knightmare Cerberus, Lyna the light charmer are probably better but I wanted to play around with Ptolemaeus a bit.
Pleiades can also be made with Gravitino and Dog Tag, it's an option I guess.
