So, maybe unsurprisingly this is going to be a dragon tribal deck. That eminence ability of the ur-dragon is just so powerful, as it doesn’t event have to be in play, it can just sit in the command zone and make all of our dragon spells cost 1 less to cast.
When we actually get to 9 mana and can cast it, a flying 10/10 that draws us a bunch of cards, and then lets us put any permanent into play will also be extremely good at ending games.
To go along with the Ur-Dragon, we’ll be playing all manner of big busted dragons, that we can turn sideways with it to win us the game.
