Basic Dexdoru

Okay here is some advice here.  I don't recommend running the Eiji in the Black Base for Dorugoramon.  The reason why Dorugoramon players run the Eiji package is because of the BT 14 Loogamon.  But the Black Base cannot run that card.  As for the Dex cards, you are running way too many of them.  Two of the DexDorugreymon from BT 17 is all you need for the Level 5 Dexs.  A 2/2 split on the DexDorugamon is what I personally recommend.  Don't run any copies of the old DexDorugoramon.  It isn't needed.  If you want to run another Level 6 then run a third copy of the new one.  It is far better in almost every situation.  Run four copies of the Dorugamon from Bt 16.  It is arguably the best card in the deck.  It helps you cycle through your cards, force your opponents Digimon to attack, and has a strong inheritable for the deck.  Don't run the Bt 13 Dorugreymon.  It has no synergy with the deck.  The restricted Bt 7 Dorugreymon is a strong card but not many people run it anymore.  I personally am using it.  Death X is a powerful card but it is overkill in this deck.  Four Kosuke is what I would recommend to make sure you see it.  Code Crackers Fang isn't a suitable replacement for it when playing the Black Base.  The Dorumon lineup is actually what I run though.  As for the Demon Wolf Castle of Nine Wolves, I don't recommend running that card here.  Even in the Purple Base it is iffy.  It is far better in Loogamon.  There is also a rule for option cards that you need to consider.  You need to have a card with the same color on the field.  If you don't have a purple card on field then that option card is useless.  And for a card that is meant to help you set up, that hurts a lot.  I recommend running either Black Memory Boost or Defense Training instead.  I also recommend running a copy of Death X Digivolution.  You can ignore its color requirements in this deck and can use it to Digivolve into the Dexs from your trash to help bridge combos.  DORU-Din is a card I see people play but if you don't have a Dorugoramon on board it doesn't do anything.  If you run it I recommend only playing one.  Metal Impulse is a purple and black option that is extremely powerful.  This deck can make use of it far more than other decks.  I recommend running a copy of it.  X Antibody and Protoform are also great cards to run in this deck.  X Antibody provides on attack evolution combos while Protoform provides reduced cost and recursion.  Pick which ever you prefer and or can afford in the case of Protoform.  DG Dimension and Ultimate Flare are two other really strong option cards you can run.  If you want to focus on a more SoC variant you can also run 2 Airdramon and two Marvin Jackson.  This will give you access to more reboot inheritables and access to de-Digivolve effects.  This helps you out against Ace cards.  The SoC Megadramon can be ran as an alternative level 5 in the deck to grant more consistency and add a little more power.  It lets you search your deck to add a card to your hand and to its sources.  It's inheritable is a when attacking de-Digivolve effect that works wonders in this deck.  These are just my own thoughts on the matter.  I play Dorugoramon a lot and it is kinda sad to see people really underestimate the deck.  And before I forget.  The purple base runs four copies of BT 14 Loogamon and BT 15 Loogamon as the primary rookies.  Most builds run four Bt 16 Ukkomon. BT 14 Bowmon as the egg.  The Level 4s are the 4 BT 16 Dorugamon, 3 BT 17 DexDorugamon, and two of the SoC Tyrannomon.  The level 5s are Four BT 16 Dorugreymon, 2-3 BT 17 DexDorugreymon (Personal Preference), and 1-2 BT 14 Helloogarmon (Personal Preference).  The Level 6 Digimon are typically a 3/3 split on the BT 16 Dorugoramon and BT 17 DexDorugoramon although I have seen people run a 4/2 split instead.  I personally run that one.  The Kosuke are replaced by the Eiji and Code Crackers Fang.  Typically 4 Eiji and 2 Code Crackers Fang.  Mist Memory Boost as a memory gain option is my personal tech here.  One Death X Digivolution for bridging combos.  The rest of the options are up to the player.  I have seen people run Jack Raid for extra memory and Protoform for added recursion.  That is all I have to say for now.  And thank you if you actually read through all of this.

Thank you for the advice, i will try this out and see how it is.
