Deck Primer

This is a hypothetical starter deck featuring Ryugumon! In the construction of this starter deck, I had a few rules:

-No cards from other existing starter decks

-No cards from after the release of the first set that the archetype was introduced in

-Try to align the chosen cards with the archetype as much as possible

-Follow the structure of ST17 and ST18 in terms of card ratios: (14) Lv.3, (10) Lv.4, (10) Lv.5, (6) Lv.6, (4) Memory Setting Tamer, (4) Archetype Specific Option Card, (2) Memory Boost

-No

-No Promo cards

For this deck, I chose to break the 2nd rule and add 2 BT22-018 Sangomon because I felt that it was better to avoid potentially whiffing Lv.3 Digimon in a card search.
