The new meta now is the meta of option cards, there are many killer options used in 3 Musketeers, Security Control, Red BOC or Blue BOF. The number of option cards is 10 to 15 cards, which is considered a lot for a 50-cards deck.
My new Ulforce deck is also using the same concept, I will slowly build up the Digimon, play more tamer and control the board by using option cards. There are 11 lv3 Digimon cards, 8 lv4 Digimon cards, 6 cards for LV5 and 4 copies of BT2 Ulforce. There are 5 tamer cards and 16 option cards.
