Basically just spam the play field with chuumon and sukamon/platinumsukamon and attack as much as possible (take advantage of chuumon's on deletion effect as much as possible) until you can use kingsukamon's effect and use that to prevent a deletion on your next security check while also deleting your opponent's digimon,
Do not bother focusing on a single stack. This deck is meant to go wide, not tall. If you can't swarm the play field with 2-3 digimon you will almost certainly lose.
Digivolve to/play king/metal etemon if there's leeway but otherwise it's better to focus on attacking and keep activating the on deletions.
