Omarthis, Ghostfire Initiate eliminates itself from the competition due to not having enough support cards: I think there's like 4 cards total that deal with +1/+1 counters in the entire deck and only 1 can repeatedly put counters (Hangarback Walker)
That being said, even with fraudulent bids being steadily removed, the card appears to be receiving a flow of genuine bids interested in acquiring it for well over $300,000 already, and it wouldn't be that surprising to see the price actually hit the $1,000,000 mark before the auction ends
Jarno put up a good fight, and in the early stages cast his Wall of Heat and later a Sedge Troll
