For most Cubes though, I love Walking Ballista as a solid card that can go in any deck that offers relevant support to artifact decks and stuff like delirium
IV seems to give this card a little more oomph than Chandra, the Firebrand did, and Im pretty sure bloodrushing a Ghor-Clan Rampager on a Phoenix is one of the dictionary definitions of a BIG GAME (TM)
In particular, what (vocal) Explorer players want are the 30-ish or so cards that would make pretty much all top-tier Pioneer decks playable on Arena
You can stick with Edgar Markov and build an aggressive Vampire deck by adding more lords, Shared Animosity, and other aggressive tribal-matters cards, or you can go with Licia, Sanguine Tribune and build lifegain combo with Sanguine Bond, Exquisite Blood, Defiant Bloodlord, and the like
Assuming youve got five mana the turn after Ojer Axonil is played, even if youve just got five spells that deal one damage each, suddenly youve got 20 damage in hand with nothing else needed
Those poor guys
