When Thanos got the reality stone, why couldn’t he use it to just spawn the other stones on his gauntlet or something. If “reality can be whatever I want it to be”, then why don’t you make reality teleport the other stones in front of you, or on your gauntlet?
In fact, couldn’t he have just used the reality stone to kill half the universe? The reality stone is basically the only stone he needs, if I were him, I would get the power stone, the space stone then the reality stone. After that, I would kill half the universe.
