Purple Beelzemon is a mill deck: it wants to dump its own cards into the trash, because almost every Beelzemon gets stronger the fuller the trash gets. Once the trash is past 20 cards, a tiny Impmon can warp straight into Beelzemon and then Beelzemon: Blast Mode, wiping the opponent's board and swinging for enough security checks to end the game in one turn.

This Red Gallantmon deck wants to flood the trash early, then unleash Crimson Mode to mass-delete the opponent's board for free. Every deletion unsuspends a Gallantmon so it can attack again, and the more cards sit in the trashes the more security each attack rips away. With enough deletions and a fat trash, one turn of repeated attacks empties the opponent's whole security stack and swings in for the win.

This Blue/Green deck builds up Imperialdramon and then reacts to whatever the opponent does. Once Dragon Mode is in play, every time the opponent plays or digivolves a Digimon you can Blast Digivolve into the Fighter Mode ACE for free, instantly sending one of their Digimon to the bottom of their deck. By attacking with that same ACE you bottom-deck a second Digimon every turn, grinding the board to nothing while you take security.

This Yellow Royal Knights deck wants to stand up an indestructible Magnamon X and then attack over and over in a single turn. You feed it cheap Yellow Options that trash YOUR OWN top security card — every time a security card leaves a stack, Magnamon X re-fires its [When Digivolving] effect, which unsuspends him so he can swing again while staying unaffected by your opponent's effects. You spend your own security to power an unstoppable chain of attacks that strips the opponent's security to zero.

This is a mono-Black control deck that buries piles of cheap Vemmon under its Digimon so each evolution costs far less than printed, letting it slam down the giant Mega Galacticmon ahead of schedule. Galacticmon deletes the opponent's board for free and drops a Ragnarok Cannon, which strips the opponent's Security down to a single card. With the board cleared and Security gutted, one swing from the 14000-power Galacticmon checks the last Security and finishes the game in a single turn.

This Yellow Hybrid/Tamer deck floods the board with Tamers and Hybrid Digimon, builds up a fat trash and security stack, then "free-warps" — it pays no memory to evolve, instead burying 10 Tamer/Hybrid cards under the deck to slam Susanoomon straight onto a Tamer. The payoff is a Level 6 that deletes a blocker on the way in and checks 4 of the opponent's security cards in one swing, closing a control game out of nowhere.
