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 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.
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.
A Blue MirageGaogamon deck that deliberately STUFFS the opponent's hand full of cards, then bursts into the Mega MirageGaogamon: Burst Mode. On digivolve it bounces the opponent's blocker, and its attack trigger forces a hand that's 9-or-more cards down to 8 — and as a reward it unsuspends to attack AGAIN. Each unsuspend means another Security check, so a single big Digimon checks Security over and over in one turn to close the game.
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 Seven Great Demon Lords deck stalls the game while dumping cards into its trash, then uses Gate of Deadly Sins to play its big Demon Lords cheaply. The payoff is Leviamon X Antibody: when the opponent's own effect plays a Digimon or Tamer, Leviamon leaps out of the trash for free and deletes a whole row of their board, so every play they make gets punished. You grind the opponent out with repeated free removal and oversized Security checks rather than racing for a single kill.
Seven Great Demon Lords is a Purple control deck that dumps its big Mega Digimon into the trash early, then reanimates them for free to grind the opponent out. This line uses Gate of Deadly Sins and Lucemon: Chaos Mode to set up, then Ogudomon to wipe the opponent's whole board AND strip their security to zero in a single turn — so the follow-up attacks end the game.
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 Green Plant deck floods the board with cheap Vegetation Digimon, then taps (suspends) them to power up BloomLordmon. Every suspended plant gives BloomLordmon free memory, extra power, and Security Attack +1, so it swings into security multiple times with Piercing for a huge beatdown. It is not a one-turn kill, but it builds an overwhelming attack over a couple of turns.
Xros Heart is a swarm deck that puts several small Red/Blue Digimon on the board, then fuses them ("DigiXros") into a single huge Mega for almost no memory. This line stacks OmniShoutmon and friends, pays the DigiXros discounts to drop Shoutmon X7 nearly for free, deletes a blocker on the way in, and swings with bonus Security checks to crack the opponent open. It does not kill from an empty board — it wins by snowballing a wide board into one unanswerable attacker.
This Royal Knights deck wins by repeatedly putting Sistermon Digimon into play for free, and every free play makes your attackers hit harder and check more of the opponent's security pile. The plan is to grow a Huckmon in the egg area into Jesmon GX, then chain attacks where each swing free-plays a Sistermon, pumps your Mega, and chips through security a card at a time. It is a grind, not a one-turn kill — you snowball board presence and security damage until the opponent runs out of cards.
Blue Hybrid wants to skip the slow evolution ladder: it stuffs Koji's Tamer with Hybrid cards and warps straight into MagnaGarurumon, a level 6 that bounces an enemy Digimon back to hand every turn. Each time a card is added to your hand, MagnaGarurumon unsuspends and Koji's inherited effect refunds memory, so you get an extra attack every turn instead of just one. The line either grinds the opponent's board down turn after turn, or warps once more into Susanoomon to wipe a blocker and swing for game.
Red Hybrid is a deck that loads its trash with Hybrid Digimon, then uses the Tamer Takuya Kanbara to "warp" straight into the big level 5 EmperorGreymon for a cheap cost. EmperorGreymon attacks with Blitz (so it can swing even while the opponent has memory) and un-suspends itself every time it gets blocked, letting it check security over and over in a single turn. The plan: fill the trash, snowball memory back from the warp, and rush the opponent's security down in one explosive turn.
Black Cyborg is a grindy ramp deck: you throw your level-5 Cyborg Digimon into the trash on purpose, then a single Machinedramon scoops five of them back under itself for a huge burst of memory. From there you stack up into the two Chaosdramon megas — one wipes the opponent's board, the X-Antibody version refuses to die and shreds their security every time you try to remove it. You don't kill in one turn; you build an unkillable 13000-power wall and slowly bury their security.
White Royal Knights is a control deck that stalls behind free Blockers while it stockpiles Royal Knight cards in its source pile, then snowballs into a single overwhelming turn. The payoff is Omnimon (X Antibody): when it digivolves it deletes every other Digimon on the table, leaving only your Omnimon, and bottom-decks one of the survivors so the opponent can't get it back. With an empty board in front of you, Omnimon swings unopposed and tears through security to close the game.
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.
