Non-Creatures Might of the Meek: This card is obviously better in a Mouse-focused deck, but I suspect an instant-speed cantrip that also gives a creature trample has its place in a variety of Red deck.s Rabid Gnaw: An instant speed punch is already good
You keep reading, and Gwenna, Eyes of Gaea keeps getting better
It's also an interesting black draw in a multi player format like commander, where you would have options for how many cards to draw (and life to lose,) based on the chosen player's graveyard
You can deal damage every time you cycle or discard a card for other effects
This commander doesnt do all the work for you, but it keeps the game moving along quickly
Howltooth Hollow If you can align the planets to Howltooth Hollow, pay the and have hidden away a great card, good on you
