Is there an entrance fee for events or are they free?

Indeed all events have a fee. It just depends on the event. Draft for magic for example is about 12 bucks.pre-release drafts will run you 20. It just depends. However, there are always free to play tables.

Last question: How much is the fee?

For the events there is a fee. To free play it's free to play at all times. Like you can just hang out and play people in yugi oh and Pokemon. You don't have to play in the event. Since its Yugi oh and Pokemon day, that s a good day to go down to the store to play yugi oh and pokemon

I'm pretty sure all of the events have a small fee.
