Well here is the thing. This deck is toxic. I wanted to find a way to break Ravemon and found that the new Level 5 that was meant to support Barbamon actually works quite well in Ravemon as an alternative Level 5. It can revive Digimon from trash and trash cards from your opponents hand due to its inheritable. It can trash a card from your opponents hand or gain a memory on Digivolve and on deletion. This is particularly nasty when used as a sacrifice for different effects. Then there is the Blackgatomon which can delete your own Digimon to prevent an attack. It also helps set up the trash while being a blocker with retaliation. It even has it as an on deletion effect. Then there is the matter of the Demidevimon. I want to have enough avian trait Digimon to have as search targets for Falcomon. That is why there are only two of Demidevimon. But it can help get you more cards in hand or rip cards out of your opponents hand. MoonMillenniummon is an excellent Level 7 for the deck as a way of simply ripping a board apart and having more hand control. Death X is a nasty card to help deal with larger boards. And since you are playing your Digimon back quite often you don't have to worry about running out of gas that quickly. Then there is Ravemon Burst Mode. I personally just want to use it despite it not being the best anymore. The ability to trash security while gaining a lot of advantage from your inheritables and creating a situation where your opponents have to worry about your cards just reviving can be quite tricky. The name of this deck is actually quite simple too. Karasu is Japanese for both Raven and Crow. As a result it is a name quite suited for this deck.
