On PriceCharting, you'll be able to see the prices of certain Pokemon cards, with a helpful graph showing the price over time
We have a bunch of viable 3-mana artifacts that can ramp into Ugin (and then trigger his static ability to exile an opponent's card once he's in play) but don't forget about Hedron Archive as a low cost way to jump from 4 to 6 mana (7 with your land drop)
When played, he will boost the Active Ninetales, Rapidash, or Magmar's damage by 30
There will need to be a personal or communal selection of land cards, so that players can build a 40 card deck from the 42 card selection, including extra Land cards to ensure they can power their spells
This is the best use for Lightning Greaves in the deck, as it'll ensure it is safe from removal and be able to attack as soon as you cast it by giving it haste
Perhaps a future event lets us win Commander precons for bunch of Brawl wins
