First get [BT14-082 Tai Kamiya] ready while breeding [BT14-007 Agumon].
After you've moved [BT14-007 Agumon] to the battle area, use its effect to digivolve into [BT14-012 Greymon] without paying the cost!
Power up Greymon with [BT14-082 Tai Kamiya]'s effect and attack your opponent.
Once it digivolves into [BT14-076 SkullGreymon], trash MetalGreymon cards from your hand and get [BT14-090 Dragon of Courage] ready!
Your next Agumon can immediately warp digivolve using [BT14-090 Dragon of Courage] or [BT14-101 WarGreymon]'s own effect! Claim victory through the power of courage!

First take advantage of a Digimon like [BT14-023 Ikkakumon] that can trash digivolution cards and reduce the number of powerful digivolution cards under your opponent's Digimon. Once their total digivolution cards have decreased, [BT14-002 Bukamon]'s effect gives it <Jamming>. Then, attack with a level 4 Digimon like [BT14-023 Ikkakumon].
When your opponent attacks, <Blast Digivolve> into [BT14-026 Zudomon ACE]!
Remove even more digivolution cards when countering, and return opponent's Digimon with no digivolution cards to their hand.
Once you've reduced your opponent's security stack enough, digivolve into [BT14-029 Plesiomon], then trash their digivolution cards and use unsuspended attacks to claim victory!

Be sure to play [BT14-084 T.K. Takaishi] early in the game! Prepare cards in your security stack for digivolving using [BT14-093 Emissary of Hope] and try to save up your memory!
After you've digivolved into [BT14-102 Angemon], you can attack and reduce your opponent's security stack, and you can use the When Attacking effect to remove an opponent's Virus Digimon or low-cost Digimon.
Toward the end of the game, use [BT14-037 MagnaAngemon ACE] to recover security cards and use the DP-reducing effect to weaken or remove opponent cards. Then use [BT14-041 Seraphimon] for security recovery and <S Attack +1> for offense!

If you use [BT14-044 Palmon]'s Start of Your Main Phase effect to give an opponent's Digimon a "When this Digimon becomes suspended, lose 2 memory" effect, you can take advantage of [BT14-085 Mimi Tachikawa] or [BT13-100 Yoshino Fujieda]'s effects and digivolve that Palmon into a level 6 card such as [BT14-053 Rosemon]!
If you use [BT14-053 Rosemon]'s effect to suspend an opponent's Digimon, the "When this Digimon becomes suspended, lose 2 memory" effect that was given to your opponent's Digimon by Palmon's effect will activate.
Then build up enough memory so you can perform your next digivolution or digivolve into [BT13-060 Rosemon: Burst Mode] and quickly reduce your opponent's security stack.
Use an accelerated digivolution to let a rose of victory bloom!

Early in the game, try to digivolve into [BT14-068 Brigadramon] while using [BT14-056 Cargodramon] to search for the needed cards!
Use new cards such as [BT14-060 Hi-Commandramon], [BT14-064 Cargodramon], and [BT14-068 Brigadramon] that can place Digimon in order to gather cards with the D-Brigade trait.
Activate <Mind Link> on [BT14-086 Satsuki Tamahime] so you can safely use the placed Digimon to attack.
When you get close to the end of the game, use your powered-up cards in the battle area and [EX3-054 Darkdramon] to fight your way to victory!
