Only 13 of the Historic Anthology V cards are common or uncommon, and a fair number of them don't fit into the cube's themes (Into the North, Ancient Grudge, etc.)

This leaves Grisly Salvage, Intangible Virtue, Merfolk Looter, and Whirler Rogue.

Grisly Salvage fits right into 's graveyard shenanigans while replacing Poison-Tip Archer, which never really fit, and Merfolk Looter replaces Soothsayer Adept as a more powerful option that lacks the mana activation.

Intangible Virtue initially appeared in a token light set, and has continued to show up in sets where it's impact is minimal, I think it's best to keep this card out for now, especially since the go wide deck seems to be one of the best decks in the format.

I could go either way on Whirler Rogue, for now it's being left out since the archetype it fits in the best is , and that archetype appears to be one of the stronger ones as well.
