Got the answers for the questions here that we asked and that we gathered from Twitter. This will release soon, and we will have some events for it in the store.
Q: Will the commander cards be over sized?
A: Yes.
Q: Can you use other Legendary Creatures as commanders or only the over sized cards?
A: Yes you can. The over sized cards are just a neat extra.
Q: What happens when an over sized card gets condemned?
A: There will be standard sized commander cards so that if they get shuffled into the deck you will be able to use them in EDH.
Q: How many Commander Decks can we expect?
A: 5 Decks. Each deck will be 100 cards, have around 18 rares, and 51 unique cards.
Q: When will the decks be available?
A: They will be in stores in June.
