cards like iron maiden mtg Iron Maiden Mtg Secret Lair x Iron Maiden:

Embark on a journey to Zanarkand with Tidus

Mono-black cards like South Wind Avatar can support these strategies, but its most often used in sacrifice strategies with Blood Artist or Zulaport Cutthroat, or with commanders like Vito, Thorn of the Dusk Rose

I look forward to her next card, most likely as a Spirit

The card that you're sure is going to change the face of Standard, dominating the format and forcing Wizards to make bannings

I also like this in shells like Discard-Matters combining this with Megrim effects, Reanimation, Midrange that wants card advantage ETB triggers, Blink that wants to have ETB stuff to blink over and over again and +1/+1 Counters-Matter where this is a nice way to add counters onto an ETB body

You can also grow a Protean Hydra by removing a counter before each opponents end step, creating a potential monster quickly
