2 Playables / 20 Cards Trusty Packbeast is more of a roleplayer in draft style Commander decks, but could very well have a place in white blue builds that need a way to get important artifacts back into your hand
Aclazotz, Deepest Betrayal and Ojer Taq, Deepest Foundation both seem like win more cards in their archetypes, and thus will show up in EDH decks on those themes (they give me heavy Erebos, Bleak-Hearted vibes)
Then there are a couple pieces of interaction (and anti-interaction?) between Swan Song, Heroic Intervention and Asceticism
All of your nonlands are now artifacts in play, and elsewhere as well like you your graveyard, hand, library, Command Zone and exile zone
Vegetables are the mana sources of a deck
