Since even Kanami noticed the power of Blackwing decks with DPE a new banlist was introduced to hit the consistency and recovery options of the archetype ;-) The DPE package was great for having a fallback option if you don’t draw the right combo pieces, you start with nothing else than just both garnets (Raider's Wing + The Phantom Knights of Silent Boots) or the opponent used Infinite Inpermanence or Effect Veiler to stop the usual combo of a Blackwing deck.

Here’s one example duel where the deck started with non combo hand: https://www.youtube.com/watch?v=ERzOxQ-s8fw The 'Draw 2 cards' in the next turn helped the deck to recover and thin the deck to draw Blackwing - Simoon the Poison Wind or other combo enablers. With just one Fusion Destiny both Destiny HEROs now immediately turn into bricks after the single Fusion Destiny is gone and the DARK Level 4 Destiny HERO - Celestial which could be used for combos if you draw it is now also banned.

If I have some time left I'm trying to build and test a Blackwing deck with 1x Crystron Halqifibrax, 1x Mecha Phantom Beast Auroradon, 1x Deskbot 001 and 2x Blackwing - Oroshi the Squall as an replacement option for the DPE package :-)
