"“If they don’t put a restriction on using the familiars, both sides will just have a battle of familiars during the game. A game where they don’t stand in the frontline and instead have their familiars battling for them……which will turn into a simple battle between familiars rather than a battle between servants.”

He’s exactly right. If the usages of familiars are unrestricted, then they can just summon them from the safety zone and attack the opponent by giving orders."

"“That’s why, for most times, familiars that are only handy can be used during the game. Of course that isn’t everything to it. Depending on the rules, it’s not like you can’t use powerful familiars. Except there will be a restriction on using it, and you can say that it might be easier to use them to their fullest by making them your servant. You can also use the power of the piece to enhance their ability. It’s also true that the importance of the monsters have risen instantly, ever since the game and evil pieces were created. Because of that, occupations as instructor called familiar trainers were created.”"
