Puppetmon seems to be main defense player for any Rookie Rush Deck. You will use 2 or 3 rookies to attack your opponent security in one turn, then next turn your opponent need to destroy your rookies, more opponent's digimon rested in your next turn. Then this is the right time to summon Puppetmon to delay opponent attack for 1 turn.
The Spiral Masquerade is a new option card in BT5, and soon to be key player in yellow Rookie deck. For each digimon you have in the battle, 1 of your opponent's digimon gets -3000DP for the turn. So if you have 4 digimon in play, you can deduct up-to 12000DP to 1 opponent's digimon, strong enough to destroy 1 LV6 digimon.
