This card synergizes really well with Delina, Wild Mage, where dice rolls matter much, so you can really benefit from playing these two together
Its doubtful that any will surface from WOTC, and TPC has much better controls over these type of items
This was widely seen as a mistake, even by MTG's Head Designer Mark Rosewater, and since then WotC has been much more careful when printing partner commanders, instead focusing lately on cards that can only be partners with one other specific creature
Theres nothing truly spectacular about these decks that makes them deserving of that amount of money
All in all, I was happy with my deck choice: Creatures (1) Planeswalkers (5) Lands (27) Spells (27) The biggest innovation that is unique to my Esper Control list is that I moved in a more black-heavy direction in favor of playing the full four copies of Heros Downfall
