Rulings:

• 5/1/2007 You choose how the damage prevention shields will be divided when you put the triggered ability on the stack.
• 10/5/2018 You can tap an untapped creature you haven’t controlled continuously since the beginning of your most recent turn to convoke a spell.
• 10/5/2018 Convoke doesn’t change a spell’s mana cost or converted mana cost.
• 10/5/2018 When calculating a spell’s total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated.
• 10/5/2018 Because convoke isn’t an alternative cost, it can be used in conjunction with alternative costs.
• 10/5/2018 Tapping a multicolored creature using convoke will pay for <img src="/Handlers/Image.ashx?size=small&amp;name=1&amp;type=symbol" alt="1" align="absbottom" /> or one mana of your choice of any of that creature’s colors.
• 10/5/2018 When using convoke to cast a spell with <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its mana cost, first choose the value for X. That choice, plus any cost increases or decreases, will determine the spell’s total cost. Then you can tap creatures you control to help pay that cost. For example, if you cast Worldsoul Colossus (a spell with convoke and mana cost <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=G&amp;type=symbol" alt="Green" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=W&amp;type=symbol" alt="White" align="absbottom" />) and choose X to be 3, the total cost is <img src="/Handlers/Image.ashx?size=small&amp;name=3&amp;type=symbol" alt="3" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=G&amp;type=symbol" alt="Green" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=W&amp;type=symbol" alt="White" align="absbottom" />. If you tap two green creatures and two white creatures, you’ll have to pay <img src="/Handlers/Image.ashx?size=small&amp;name=1&amp;type=symbol" alt="1" align="absbottom" />.
• 10/5/2018 If a creature you control has a mana ability with <img src="/Handlers/Image.ashx?size=small&amp;name=tap&amp;type=symbol" alt="Tap" align="absbottom" /> in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell’s costs. You won’t be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won’t be on the battlefield when you pay the spell’s costs, so you won’t be able to tap it for convoke.
