Dragonskull summit

[An Angry Fatman]

Aight so I know the rule that {dragonskull summit} searches for the mana produced by other mana cards. So let's say first turn I drop a dragonskull, it comes into play tapped. Second turn I dropped a second dragonskull and it comes into play untapped. What rule states this? Got into a major fight at my shop today about this and I knew I was in the right but I got over ruled by majority.

It says on the card. And it comes into play tapped. "Comes into play tapped unless you control a mountain or a swamp".
{Dragonskull summit} is niether.
You would need a {Swamp} or {Mountain}, a shock dualie with either type or similar.

Also this was meant for rules right?

It doesn't. It states "swamp or mountain"

{dragon skull summit} type is land

{blood crypt} a RTR land, would count as both and if you dropped it t1, t2 dragon skull would come in untapped.

{Dragonskull Summit} is a land that produces {B} and {R}. It is not a swamp and it is not a mountain.
