Like regular CS engine use Palmon, terriarmon and hagurumon inheritage effect to put top card to bottom then have ami, Wanyamon and Goldnumemon so you can get into leevl 5 without even paying cost.
Togemon main effect +3000DP and it's second effect raid and pierce and it's inheritage +2000DP will make your Craniamon turn into 16000DP also since Craniamon second effect it's all turn meaning you can also activate by attacking since this also count as suspended, you not only delete one of their highest digimon and security check 1 but also delete other digimon with lowest cost.
Lilamon can suspend one digimon including your opponent and it's inheritage if you destroy opponent digimon during battle trash top card and it's all turn meaning you can use this to raid on one of your opponent and on opponent turn since it have reboot it will unsuspended and if your opponent attack it will activate it inheritage again. Weregarurumon force one of your opponent digimon to attack this help Craniamon effect, with it inheritage de digivolved also give more lowest play cost digimon on opponent field. But use this only when you want to clear your opponent remain field, don't always force your opponent attack and block their attack just activate craniamon second effect since Craniamon first effect can protect your digimon or tamer on field by suspending it, if it was supending after it you blocked it you will lose protection from card effect and your opponent use this opportunity to counter attack so there a time where you let them do security check and time where you block.
You can use both use Eden and Island at same time since Eden is bottom security and Island is top meaning you will get +4000DP all turn
If there only one digimon in your opponent field and during your turn, you can try to direct attack and use it effect but it risky consider this card have only 11000DP and security check could be digimon with higher dp or have effect that would destroyed you, so either set up first by using eden,Island, Yuuko, Terriermon and Togemon inheritage it will get +13000DP or you can just use <raid> from togemon to attack that and use craniamon effect in this way your digimon didn't get destroyed by security check or digimon with higher dp(but becareful cause there are card that are uneffected by card effect)
There 2 level 7 aces so you can use if you ran out of defense, Quartzmon is for more stalling but if you want quickly end on your next turn(like your opponent have 2 or fewer security card) use jesmon GX since these two aren't related to CS you can't search it with kuremi detective office and the only thing you can only get is by drawing
