There are plenty of cards that synergize with The Ur Dragon's matter-of-fact battle plan
Remember that the copy goes on the stack above the original and resolves before it
You create just one Griffin token, no matter how much life you've gained past 3 life
2: Create a 2/2 colorless Drone artifact creature token with deathtouch and "When this creature leaves the battlefield, each opponent loses 2 life and you gain 2 life." If you return a creature to its owner's hand with Kaito's first ability, you may activate a single loyalty ability of Kaito twice, or you may activate two different loyalty abilities
Furthermore, you are going to have the most variety of win conditions, and board states with this deck over the others
You can think that you belong to Power Nine because Urbogg's bigger, Yarg, is a 9 card
