All Star Trek Commander cards that arent from the main set (TRK) use the TRC set code and set symbol
If you have a lot of mana lying around and an Arcbound Ravager or Cranial Plating, you can squeeze an extra damage/poison counter out of a Blinkmoth Nexus by pumping the attacking Nexus with it and then activating it for an extra Plating power/another artifact to sacrifice to Ravager
Id look elsewhere if I was focused on a type populated by smaller creatures
So now I can replace the venture into the dungeon text with choose one: create a Treasure token, target creature cant attack until your next turn, each player loses 2 life unless they sacrifice an artifact, a creature, or a land, put a +1/+1 counter on target creature, each opponent loses 1 life and you gain 1 life, or target creature gets -4/-0 until your next turn
I started out okay, not great, and started slowly cranking out a couple Caribous
I would expect to see Grief out of decks such as Jund, Deaths Shadow variants, Orzhov Taxes, and possibly even black-based combo or Reanimator decks
