Mega Lucario ex Well see if Lucario ex ends up being competitively viable
The new Job Select mechanic is especially neat, arriving in the form of Equipment cards that generate Hero tokens as they enter, essentially giving the casting player a free (albeit low-powered) creature and skipping the equip cost
There are previews of some neat Double Faced cards, which can show two sides/forms of a particular character or creature, with the examples used including Garland, Knight of Cornelia which flips to become Chaos, The Endless , and Cecil, Dark Knight becoming Cecil, Redeemed Paladin (spoilers!)
The aforementioned Corpses of the LostCorpses of the Lost also works well here, letting us surprise our opponents with a big, hasty creature to close out games
So if you attack or block with a creature that has first strike, that card will deal damage first and will not take into consideration any damage being dealt by the opposing creature
