With the advent of BT5 came along great support for the Diaboromon strategy, be it with Digimons from the Lv2 Tsumemon all the way up to the Lv7 Armageddemon and every level in between, a personalized tamer with Arata Sanada and 2 options that obliterated rookie strategies or created more Diaboromon tokens.
Unfortunately none of these cards fixed a very glaring and core weakness, not only for Diaboromon decks but for any Black deck for that matter, that is to deal with hard played Digimon that cost 8 or above. The premiere example of this is BT5 BlackWarGreymon, that when hard played is almost impossible to destroy with a pure Black deck with the exception of a 12K or higher blocker.
To cover for this weakness I’ve seen and tried many hybrid Black decks but none played to the strengths of the Diaboromons strategy. Such was the story up to the 21th of April when in Japan a tamer with the name of H.N. Tsurugi won a tournament with a Diaboromon deck with a tech I’ve never thought of and in my opinion is the single biggest game changer for Diaboromon decks since the release of BT5.
