I use "Changes the value of all cards to 9" then "Increases the value of all cards by 2". What happens is that all cards will be changed to Wild Cards. And if you've a little bit experience you can manage to get more than 4 chains everytime. I can OHKO most of the bosses
My team that has these abilities are Alphamon SP and Omegamon Zwart but any Digimon with these abilites are ok.
I hope this will help you.
