Tenacious Underdog For a while, Tenacious Underdog has been one of the best 2-drops for black decks to run in Constructed formats because it has a reasonably substantial body that threatens opponents for massive damage very early in the game and its blitz ability can be used from the graveyard
Its an excellent glue card for many strategies: a good target for Birthing Pod, high-toughness, untapping is pseudo-vigilance, ramp, discard for graveyard value/reanimate, blink, the list goes on
The most glaring weakness of the werewolf creature type is that if two or more spells are cast in a single turn, all werewolves will transform back into their weaker forms
I expect that to be all turned on its head once people get their hands on the product and get to brewing with the new sweet creatures
Leaks change card prices
At first glance, Stitch in Time seems like one of the joke cards from Unglued or Unhinged series
