Which do you like more?

[void_nothing]

Bonders' Enclave - I don't tend to play monocolored or colorless decks.

or

[materpillar]

Diabolic Intent you can do some neat things with the sacrifice. Grim Tutor is just a mediocre goodstuff tutor.

vs

[Jemolk]

Primal Surge is way more interesting and requires building around it, which makes it a much better design in my book than the original "search for Mike & Trike, win the game" one card combo of the format.

Teferi's Protection vs Guardian of Faith

The guardian is at least theoretically reusable.

[Myllior]

Guardian of Faith. Borrowing the expression from 3drinks in the Community Deck Build Thread, Teferi's Protection is an example of a "boring, egregiously expensive card".

or

[Gamazson]

Assuming mono-red; Invoke Calamity for mana efficiency.

or

[Mookie]

Mists of Stagnation. If I want my opponents to suffer, it better actually be effective. Throw in Leyline of the Void for some one-sided Stasis shenanigans.

Best white value 2-drop?

vs

(unless you think something else is actually better)

[Treamayne]

Not every W deck needs equipment, but nearly every one can benefit from the Ramp.

Combat Shenanigans

VS

[Jemolk]

Baton of Morale. Banding is such a wonderfully screwy mechanic. I love it so much. It's not even as complicated as it looks at first glance; its problem is simply that reading the card doesn't explain the card, because even the reminder text would take multiple paragraphs. In the age of the internet, that's not as big a problem as it was in 1994.

Welcoming Vampire or Mentor of the Meek

[void_nothing]

Welcoming Vampire just personally. I'm sure this would be reversed if I had Ghave, Guru of Spores at the moment, but my Doran has few tokens and many low-power creatures.
