As with the Daring Apprentice and Temporal Adept, this small, 1/1

creature is very vulnerable, but packs a powerful ability. Playing it against

red will always be a very risky option, and you'll want to be setup with

counters, in that case. Another option is to prevent any in-coming

damage with white healing-spells, the most classic example being the

Samite Healer. There are other, more effective healers that appear later

in the game's history, so simply search "prevent" and "damage" in the

Card Gatherer at gatherer.wizards.com (Also, add "noncombat" to check

out powerful spells that can cover your creature base). Of course, your

problem might also be black, creature-destruction spells... I would say,

being such a small target (despite the ability), Archivist is something that

you can let go, in many cases. It might actually be a positive, strategic

decision to allow your opponent to target your Archivist, and then drop

something more dominant on to the field. The fact that it can draw an

extra card per turn will draw your opponent's attention, making it a good

way of pulling the kills out of their hand.
