I have been crushing the Arena ladder with this deck recently. Just reached diamond with it last night after a couple of days of play. One of the main reasons for this is that the deck does very well against mono red (which is encountered a lot in Arena). The main goal of the deck is to abuse the ETB card draw and life gain effects with Thassa and Charming Prince until you can land a finisher. You can also permanently steal cards with Thassa after they have been captured with Akroan War. The deck has a decent match up against control swapping out the creature removal for counter/exile magic. Any thoughts and input welcome. Thank you.
