mtg commander energy deck - Aetherdrift Living constructed 100 Aetherdrift Living Energy Precon Upgrade

Let's say Do-It-Yourself Seraph has the text boxes of both Beast of Burden (power and toughness equal to the number of creatures on the battlefield) and Psychosis Crawler (power and toughness equal to the number of cards in your hand)

His ultimate will allow you to create five 4/4 flying Dragon tokens

Together with Animation Module and then either Phyrexian Altar or Ashnods Altar, you can have yourself infinite +1/+1s counters put onto Feral Ghoul, which whenever you decide to stop, can then be transitioned into an-amount-of-your-determination Radiation counters onto your opponents, causing them to all effectively lose the game on their upkeep to both mill and life loss

Instead, you can have many fairies to take advantage of the increase

I suspect that mildly poor scaling with other Doom Blade restriction removal (which is the most frequent limitation on black removal) is what keeps this at the lower end of the "amount of play" ranking tables
