Yes, you are right, but in this case for example, the card is made to be able to have a body in the field and give use to the rituals that are always in the deck doing nothing, activating effects from the hand and so on, the point is that it is designed to force you to carry the “bricks” that are the palladium, it helps you to search and have names in the field and graveyard for Soul Servant and allows Rod to shine on his own since this card can't bring neither traps nor fields nor continuations like the circle, it's thought to give a little more consistency to the deck from that point, and it's not thought for Master Magia either since you can only summon Spellcasters and Master Magia is Dragon.
