Rulings:

• 9/20/2016 If a creature that is both an artifact and an Artificer enters the battlefield under your control, Era of Innovation’s triggered ability triggers only once.
• 9/20/2016 You can pay <img src="/Handlers/Image.ashx?size=small&amp;name=1&amp;type=symbol" alt="1" align="absbottom" /> only once each time Era of Innovation’s first ability resolves. You can’t pay more to get more than <img src="/Handlers/Image.ashx?size=small&amp;name=e&amp;type=symbol" alt="Energy" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=e&amp;type=symbol" alt="Energy" align="absbottom" />.
• 2/9/2017 <img src="/Handlers/Image.ashx?size=small&amp;name=e&amp;type=symbol" alt="Energy" align="absbottom" /> is the energy symbol. It represents one energy counter.
• 2/9/2017 Energy counters are a kind of counter that a player may have. They’re not associated with specific permanents. (Other kinds of counters that players may have include poison and experience.)
• 2/9/2017 Keep careful track of how many energy counters each player has. You may do so by keeping a running count on paper, by using a die, or by any other clear and mutually agreeable method.
• 2/9/2017 If an effect says you get one or more <img src="/Handlers/Image.ashx?size=small&amp;name=e&amp;type=symbol" alt="Energy" align="absbottom" />, you get that many energy counters. To pay one or more <img src="/Handlers/Image.ashx?size=small&amp;name=e&amp;type=symbol" alt="Energy" align="absbottom" />, you lose that many energy counters. Any effects that interact with counters a player gets, has, or loses can interact with energy counters.
• 2/9/2017 Energy counters aren’t mana. They don’t go away as steps, phases, and turns end, and effects that add mana “of any type” to your mana pool can’t give you energy counters.
• 2/9/2017 You can’t pay more energy counters than you have.
