The synergy between Arcbound Ravager, Frogmite, and artifact lands is still strong as ever. As we all know, this deck is capable of getting degenerate draws. A common example is:

Turn 1: Artifact land, Aether Vial
Turn 2: Artifact land, Arcbound Ravager, Frogmite, Vial out a Disciple of the Vault
Turn 3: Vial out another Disciple, play some more artifacts, attack with all creatures, and eat everything with Arcbound Ravager to put your opponent down to a negative life total. Thanks for playing.

If the opposing deck can fend off these ridiculously fast draws, that doesn't mean the game is over. Affinity can easily reload with the extremely powerful Skullclamp, attaching it to 1-toughness creatures to draw two cards right away or to larger creatures that can then be sacrificed to Arcbound Ravager for two cards. This allows Affinity to basically draw its entire deck quickly, right into the dreaded Arcbound Ravager plus Disciple of the Vault combo for the kill.
