By using (contract) seals, you can summon different objects to fight with them. Whether it is a Shuriken, a Kunai, huger Objects like swords and other weapons or even statues like Gedo Mazo. The huge summons are going by this principle, too. So how does the contract with objects work? Are they sealing a part of this object in her seal, whether it be on their hand (like by Sasuke) or in a scroll, in order to summon it? So if you are able to make a contract with a very objects, no matter if small (Shuriken), huger (swords, other objects) or other huge things like summons you can summon from the air (remember when Jiraiya did it), what about making contracts with huge objects, similar to the meteor Madara has thrown? Or even with something like mountains or huge rocks? I think there is no limits in size since it is a space time technique which summons objects from one place to the other through a seal. So what about summoning meteors, mountains, huge water accumulations and other huge objects instead of Kunais, Shuriken, and objects from the size of a human or summon?
