Whenever Wrexial deals combat damage to a player, you may cast target instant or sorcery card from that player's graveyard without paying its mana cost
Equipment decks can utilize the latter along with Puresteel Paladin or Sram
I like pairing it with cards like Mondrak, Glory Dominus and Divine Visitation to get the most out of creating two attacking tokens, which I think should be a default mode
If another creature would deal combat damage to equipped creature, it deals double that damage to equipped creature instead
Despite how bad the set plays in Limited, were here for EDH, and theres actually a lot more to be found here than most probably think
My best use has been returning a Yuriko, the Tigers Shadow to its owners hand avoiding six reveal triggers
