Re-print of a 1st wave card, Quake is a solid Damage dealing Justice ally who is worth the cost even if you just attacked once then chump blocked.
But if you are playing a minion heavy scenario, particularly in multiplayer, she can sit as a fixture on the table, blasting minions turn after turn as players duck out to get a little rest. One of the key things to remember is that 0 Sch minions still scheme......they just don't add anything. She is a great trap ally that can deal damage to minions, even if just preliminary or ping toughs, and set them up for larger overkill hits on the following turn. If you are ever in a tough spot and need the block, she can also provide that on later turns.
Of course, with the last few campaign boxes having lots of ally mitigation and chump blocking not always being a practical option, this is a timely reprint for Justice to get more access to cost effective option at dealing damage.
