Rulings

• If you choose to pay a conspire cost of a multicolored spell, the two creatures you tap don't need to share a color with each other. Each one just needs to share a color with the spell that has conspire.
• You may pay a spell's conspire cost only once. (If a spell has multiple instances of conspire, you may pay each conspire cost only once.)
• A copy created with conspire will have a conspire ability itself. However, since that copy wasn't played, its conspire ability won't trigger. You won't get another copy.
• The copy you create with conspire is separate from the original spell. If either one of them is countered, the other remains on the stack.
• If conspire's triggered ability is countered (by the Scourge spell Stifle, for example), no copy will be created. The original spell will be unaffected.
