Aether Inspector has Vigilance and "When Aether Inspector enters the battlefield, you get two energy counters"
My illustration work for the second chapter of the TCG Disney Lorcana
While not strictly necessary or anything, if you have the room and the budget, you can do way worse than having these in the deck
So, for example, if you cast Deadpool, Trading Card and trade text boxes with and opponent's Solemn Simulacrum, when Deadpool enters you'll get to fetch a basic land , and draw a card when he dies
Its easy to shortcut this card to a three-mana 4/4 that dies to two damage in an Adventure-centric format, but yet again the key is the third chapter being more impactful than expected
They act as a Warstorm Surge (an extremely powerful enchantment), but only for Demons
