Can you tribute the same turn during a normal summon? - Answers

You can definitely tribute a monster on the same turn as a Normal Summon, ie, you can normal summon Exiled Force and tribute it for its effect. What you can't do is tribute it for a Tribute Summon because this is another Normal Summon, you can't perform two in a turn unless an effect allows you to do so. But you can tribute that monster for other things, like an activation cost or for a special summon.
