So, today I was making my Arena Deck with a Gravity pillar as Oracle card; I decided to do a mono

. I have put my two upgraded

cards in that deck: elite armagio and SoFo. I put them in and some other cards. Then I removed three (or four) otyoughs and added two Titans. Then I switched tab and finally switched back to EtG. I was surprised to see that in the deck there were two Elite Armagios and no Upped SoFo! So I removed the card that was prevously the SoFo (without taking a screen, obviously), and the card now wasn't anymore an Armagio but it was the SoFo as before. I clicked again on it an it was displayed correctly in the deck.
So, not much, but still a glitch.
