To trigger Justimon's abilities perfectly, you need to have as much DP as possible and more Tamers. If we build the deck according to the cards given in ex-02, it takes four steps to play a Tamer from our hand:
- Get a Digimon that can search for Tamers in the deck;
- Play or evolve that Digimon;
- Search the deck for a Tamer and add it to your hand;
- Play the Tamer.
Ignoring the fact that the entire process gradually dilutes the probability, in the game, the opponent will not give you enough Memory to complete this process 90% of the time.
Therefore, we focus on the new Tyrannomon component and Mamemon. They not only have the ability to search for Tamers in the deck, but also have an effect that can greatly increase DP when a Tamer is on the field, which was not available in the previous black components. The new Mamemon can evolve for 3 Memory costs to search the top 5 cards of the deck and play a Tamer with a cost of 4 Memory or less. Importantly, there are no color restrictions on these Tamers.
In addition, the new Tamer Taiga from BT-11 gives us a chance to evolve Level 5 and Level 6 Digimon without consuming Memory or consuming very little Memory, which gives Justimon a chance to activate in one turn. At the same time, Taiga can give all of our Digimon DP bonuses during our turn, giving us the opportunity to use lower level Digimon to replace higher level Digimon on the opponent's side.
There are many other considerations regarding Inherited Effects, but more experimentation and changes are needed to determine the specifics. However, based on the current available cards, selecting Level 5 seems to be the only solution. Mamemon's entry seems to have no way to trigger it, but it can be achieved by adjusting the other levels.
Apart from Taiga, Ryo is essential for selecting Tamers because the entire deck has almost no ability to search for black Digimon. To ensure Justimon can start, Ryo must serve as this search tool. For the remaining three Tamer slots, my consideration is to include Tamers that can ensure I start with 3 Memory at the beginning of my turn. After observing all the available green Tamers, I chose Mimi and Ken, both of which have a second effect that can be triggered.
The selection of Digi-Eggs was based on the consideration of Darw Card and adding some DP to the deck.
The deck has a lot of green cards, so we try to carry green Option Cards to ensure that we have room to use spells. Flower Cannon is an Option Card that can be considered for addition to the deck because it can force the opponent's Digimon to suspend themselves, then we can use our Digimon to kill them and limit the opponent's growth.
