mtg you may play cards from your graveyard The Gathering - Planar Chaos - Shrouded Lore Conduit of Worlds | Phyrexia:

Whats the coolest custom card youve come across

A 1-mana stax piece

You couldnt see the whole pack, but you could easily make out the front card and sometimes even the rare if you tilted it right

We chose the Veloci-Ramp-Tor deck because it ramps aggressively into dinosaur tribal strategies, creating fast, high-impact combat turns

You can cheat out bigger things like Darksteel Colossus and Consecrated Sphinx

I imagine something like Entomb to tutor up a Bolas's Citadel, then casting Mox Amber to reanimate the Citadel and popping off from there could be a good start at what Moira can do, but I'm sure people can come up with far scarier lines than my quick example
