Heres an example: You have a Gliscor LV
No casting, which evades most counterspells, and the only limit to the number of times you can use it is the mana you produce
For all of the decks that have tokens coming in swinging, you can still assemble the wombo-combo of Renewed Solidarity + Iroas, God of Victory, or Reconnaissance, or Dolmen Gate, anyways
Since we cant put this djinni back in that bottle though, I hope that Wizards puts on their thinking caps and figures out how to make energy cards in a way that constrains some of those automatic advantages, just as they did with those broken phyrexian mechanics before
This one is a bit of trouble to set up and is a straight dead card in topdeck mode and laughable against swarms of aggressive Boros and Gruul options that will run over a player trying to get this attached and online for a potentially useless return
