Forum:Tiki Deck questions

I have a few questions about tiki trap monsters and the rules with a few cards.

1. Do trap monsters still fill a spell and trap card zone?

2. If i have tiki's face up on the field in the monster card zone, and i have imperial custom on the field face up, does imperial custom effect the tikis?

3. If i have spirit barrier on the field as well, do i still take battle damage with the tiki cards?

Thank you for your time.

Sincerely,

Shadowman
