Forum:Inherent Summoning rule

Ok I know of this rule but I would like someone to help me better explain when and why this comes into play. I means its this rule that you can chain to Future Fusion with things like Oppression. I just need to know how this rule works better to know how to deal with it and exploit it in the future 68.40.106.199 (talk) 00:16, August 27, 2010 (UTC)
