Jazzock. I do know that A2 has very very few return cards, but all of them have conditionals and are not worth it, as A2 also has grims that can summon a unit instantly onto the field.
Icy: Confused by Calonia? I mainly play A2 and Lavato Heroes on the jp server. I've never once seen a single return card or send to cemetary card played(Unless of course it was a file destruction file which sent them from file to cemetary. Not from field.). There are a ton of max hp hate and set cards hp = 0 though. The only cards that get sent to cemetary from field from my experience are the new sphere. The new spheres close skill sends them to the cemetary automatically.
