Remember that they are the MCU version, not the comics one.
Also, if sometime you want to use them, remember about their actual capacibilities and the possible side effects while using (e.g., hold the power stone will disintegrate you, if a powerless being hold the Reality Stone, it will inevitably kill you, etc.).
@MizzDohCare Yeah, I think that the only dangerous stones are the Power Stone and Reality Stone (the first one will disintegrate you and the last one will inevitably kill you), the others seens to not have such side effects.
So I choosed the Mind Stone because of their capacibilities, and if it's possible, I'll prefer to have the Scepter as well, to look cool XD
