When the conditions are met, digivolve into [BT5-087] Omegamon Zwart by using Fuse Into The Ultimate Digimon! for 0-cost. This will allow you to revive 2 8-cost or below Digimon from your trash. Ensure that at least one of the revived Digimon is a LV5.
Combo note: you can revive a Kimeramon and a [BT5-071] Guilmon to delete an opponent's LV5 or lower Digimon, while deleting your own revived Guilmon to gain +1 memory.
Attack with Omegamon Zwart to delete an opponent's 12-cost or lower Digimon by returning your LV6 digivolution card to your hand.
Digivolve the LV5 Digimon that you had revived into [BT3-091] Lilithmon to return 2 Jack Raid option cards to your hand. Make sure you have at least 3 memory before you digivolve so that your turn does not pass (play Jack Raids). Play 2 copies of Jack Raid to gain a total of at least +4 memory (2 from Jack Raid and another 2 from Lilithmon's effect).
Repeat this Lilithmon loop if you have more copies of her in hand, and end your turn by normal digivolving into another Omegamon Zwart, allowing you to play 2 more Digimons from trash while giving your opponent little memory (due to all that looping).
