Why Play Medusamon Dragonkin?
Medusamon was the best deck in the BT-24 format by a wide margin — 16.68% meta share across 306 tracked tournaments, more than triple the second most popular archetype. That kind of dominance does not happen by accident.
The reason for its success is deceptively simple: the deck attacks through almost everything. The Progress keyword makes Medusamon and Lamiamon immune to opponent’s effects while attacking — no Megadeath security traps, no Retaliation, no removal options on the stack. Combined with Cyberdramon forcing your opponent to trash security and discard from hand, the deck strips resources while pushing security in the same sequence.
⚡ The BT-25 Question
Dual Revolution’s restriction list hit Shakkoumon and MaloMyotismon to create space for the new format. Medusamon avoided the list entirely and remains fully legal at 4 copies. The deck is still tier 1.
The Core Mechanic: Progress
Progress is a keyword that reads: “While this Digimon attacks, your opponent’s effects cannot affect this Digimon.”
In practical terms, this means your attacking Digimon is untouchable. Your opponent cannot:
- ✓Use security effects to delete your Digimon mid-attack
- ✓Activate Retaliation to kill your attacker
- ✓Play Option cards to reduce its DP below 0
- ✓Target it with Counter effects during the attack window
Medusamon carries Progress. Lamiamon carries Progress. When you are attacking with either of these Digimon, your opponent can only watch the security get hit.
🎯 Why This Matters for Beginners
Most defensive strategies in Digimon TCG rely on security effects, Retaliation, or Counter-timing removal to punish attackers. Progress shuts down all three simultaneously. It is one of the most powerful keywords in the game.
Key Cards Explained
The Engine
BT21-029
x4
Medusamon
Win ConditionLv.6 Red Digimon with Progress. On Play and When Attacking: places a Petrification token on your opponent’s field. The token prevents your opponent’s Digimon from attacking. Stacking tokens with multiple attacks creates an impenetrable lockdown while you continue pushing security.
BT24-017
x4
Lamiamon
Evolution TargetLv.5 Red Digimon with Progress. When Attacking: if a security card was trashed this turn, you may Digivolve one of your Digimon into a Reptile or Dragonkin Digimon from hand at cost -1. Fuels explosive multi-Digimon turns by chaining evolutions mid-attack.
BT21-026
x3
Cyberdramon
DisruptionLv.5 Red Digimon. When Attacking: force your opponent to trash the top card of their security stack AND discard 1 card from hand. A two-for-one resource drain that also fuels Lamiamon’s inherited trigger. This card is why the deck snowballs so hard.
BT21-001
x4
Gigimon
Egg DeckGuilmon’s Baby form. Inherited Effect: once per turn, when your opponent loses a security card, you may Digivolve one of your Digimon into a Reptile or Dragonkin Digimon at cost -1. Works alongside Lamiamon for back-to-back discount evolutions.
Evolution Line

Guilmon
Lv.3 BaseInherited Effect: draw 1 card when an opposing Digimon is deleted. Strong inherited effect that keeps your hand full while you push security.
BT21-012

Growlmon
Lv.4 BridgeInherited Effect: when this Digimon attacks, gain +1000 DP. Stacks with other DP buffs in the line to make your Medusamon increasingly difficult to trade into.
BT24-001

Gigimon (BT24)
Egg AltThe BT-24 version with a slightly different inherited effect. Run both versions at 4 each for maximum consistency in the egg deck.
Support

Jesmon GX
Lv.7 FinisherOptional high-end finisher. With enough Dragonkin Digimon in the trash, plays for free and closes out games that go late. Not core but devastating in the right situation.
BT21-100

Spiral Trigger
OptionWhen an opponent’s security is trashed, you may play this for free from security. Adds 1 security card back to your stack. Excellent for recovering when security is thin.

How to Play: Turn-by-Turn Game Plan
Set Up Your Engine
Hatch Gigimon from the egg zone. Play Guilmon or Agumon as your Lv.3 base. Your goal is to have a Lv.3 Dragonkin in the battle area by turn 2–3 ready to start evolving. Play Dan Yuki & Kanan Yuki tamer early to start generating memory advantages.
Build the Stack & First Attack
Evolve into Lamiamon (Lv.5) — this is your primary attacker. Use the Unique Emblem: Blazing Conductor option to play Tamer cards while building your stack. When you attack with Lamiamon, you’re Progress-protected AND setting up Cyberdramon to drain your opponent’s resources simultaneously.
Fire the Cyberdramon Sequence
Evolve Lamiamon into Cyberdramon. Attack. Your opponent trashes 1 security AND discards 1 card from hand. If their security triggers, the Lamiamon inherited effect lets you chain-evolve a Reptile/Dragonkin Digimon from hand for cost -1. This is where the deck generates explosive board presence.
Medusamon Lock
Evolve into Medusamon. Attack. Place a Petrification token on your opponent’s strongest Digimon. Your opponent now has a frozen Digimon, thinning security, and a shrinking hand. Continue attacking each turn, placing tokens and triggering Lamiamon/Gigimon inherited effects to chain further evolutions. Close out with a final alpha strike when security is at 1 or 0.
💡 Memory Management Tip
This deck wants to end its turn with memory at 0 or 1 on the opponent’s side. Never spend so much memory that you give your opponent 4+ to start their turn. Plan your evolution and option sequence to leave minimum memory behind.
Matchup Guide
BeelStarmon Three Musketeers
BeelStarmon’s Blocker and Counter-unsuspend can disrupt your attack sequences. The Three Musketeers Options used for free each attack make removal awkward. Key: apply early pressure before they set up. Do not let LadyDevimon get two attacks through safely.
Yellow Vaccine Decks
Yellow’s primary strategy relies on security-based healing and counter effects. Progress bypasses most of their security traps. Their Lv.7 finishers are the main threat — remove them before they can stabilize with Heal effects.
GraceNovamon / Olympos XII
The mirror-adjacent matchup. GraceNovamon decks have powerful removal on Digivolution and attack timing but lack consistent Progress protection. Race their setup with your own. Dan Yuki & Kanan Yuki memory generation is critical here.
Black Control Decks
Black’s strength is repeated removal and DP reduction. Progress shuts down all of that while you are attacking. Their strength is recovering from your attacks — apply pressure fast and do not give them time to rebuild the board.
Purple Memory Boost
The #1 deck in BT-25 by tournament score. Purple’s memory generation allows massive turns. Cyberdramon’s hand disruption is critical here — keep trashing their hand while pushing security to deny their big swing turns.
Budget Breakdown
The main cost driver in this deck is Medusamon (BT21-029) at ~$20–30 each, Lamiamon (BT24-017) at ~$8–12 each, and the Dan Yuki & Kanan Yuki tamer (BT24-085). Here’s how to build at different price points:
Budget
~$60–$90
Replace Jesmon GX and premium Tamers with budget alternatives. Run Agumon (ST7-02) as your primary Lv.3, skip the Hiroko Sagisaka Tamers, and cut back to 2x Medusamon. The core engine (Gigimon / Guilmon / Lamiamon / Cyberdramon) is affordable. You lose consistency but the deck still wins games.
Mid-Range
~$130–$180
Full engine with 4x Medusamon and 4x Lamiamon. Add 2x Dan Yuki & Kanan Yuki Tamers. Skip Jesmon GX and premium alt-arts. This is the sweet spot for competitive play without chasing chase rares.
Premium
~$220–$280
Full optimal list including Jesmon GX finishers, alt-art Medusamon, and the full Tamer suite. The deck at this price is a legitimate regional-level contender.
