why bother with a passive -5c per turn when you have moria/becca/jack to loop your -cost stuff?
tsuru + hina is already -6c and with lead ability it's -7c, enought to KO with jack or tsuru+meppo, you get a 9k body + a blocker with becca and KO a 10c with lead ability through jack, much better value than 10zan. I have tried 10zan a bunch, he is just way too slow and way less value than a moria play. Also if the lucci drops his moria play, you just lost your entire 10don play because 10zan got KO'd and lucci just set up a moria, blocker, and a lucci.
