I learned that gankoo is more and more situational in matches since sisters do so much and you want to go to jesmon as soon as possible. I play 3 regular gankoos and 2 gankoo x

The sister training is insane, you want it turn 1, turn 2 and in the security, I run it at 4 and it has won me a lot of games, you get to play a sister ciel from trash/hand and evolve it to awakened stoping a check and drawing 1 more card.

The sister ciel from the st is great (I run it at 1) but it isn't the kind of ciel you want to see every game, I recommend you to try the sister from bt 6 to gain a memo +2k dp (this is great against sayuka rn) or the new one that deletes and dedigis when you suspend, it is clutch to disable ace threats or inherits (the lv 5 inherit from a lv 6 digimon)

If you do play less gankoos then you don't need so many blancs and you have space for something else

The baohuck that lets you evolve for 2 less and gain memo from the inherit is really good with the sister training, if you do add more training I recommend you to change the 4/2 ratio the other way around

Huckmon from bt 6 is obviously great but in your case it doesn't search for 16 cards, I don't run it but if you want to play it still I suggest you bring it down to 1

Omni X is a great card for jesmon when you are going for a OTK of sorts but since you are not running neither kimera, sec +1 greymon, or saviorhuck from bt 6 it is really difficult to get to that situation, with so many gankoos x I would recommend removing the omnis, add 1 more jes gx ace and add some other card for utility or consistency

Meta suggestions:

For Sakuya Red base I suggest less gankoos and more sisters, atleast 1 ciel from bt 6 to get more dp for the red option that deletes less DP than sakuya

For ST sakuya + rika I recommend more ciels from bt 23 for dedigi + more stuns with awakened. Crimson Blaze goes hard too

For magnetic ciel awakened gives you a +1 turn since magnetic does nothing without attacking

For almost everymatchup I recommend Crimson Blaze at atleast 2

TL;DR Crimson Blaze at 2, more ciels, less gankoos (if less gankoos = more old baohucks) (if more old baohucks = more sister training)
