Before Theros Beyond Death I had a Bo1 Bant Elemental deck for arena. Now with the new cards, i've upgraded it into a Bo3 deck and it rocks hard. Thassa is amazing with all of the etb triggers in this deck. I know not all creatures in this deck are elementals but they each are win cons in their own right. Agent is gross in itself, and paired with Thassa it's busted. Charming Prince is one of my favorite white cards in this entire block. It's a bear for blocking aggro and early damage against slower control. It can scry 2 for land drops, heal against aggro, or blink another creature for more etb shenanigans.
Against aggro (mainly red) i board out 2 Thassa, 2 Agents, 1 Teferi, 2 E.C.D., and 2 Reef, for 2 Devout Decree, 2 Banishing Light, 1 Archons, & 4 Knights.
The Spinners and Dispute are for counter heavy decks (on top of Thryx, and Teferi they're not countering anything XD).
Archon of Absolution murders U/W control. All of their removal and dmg comes from white sources. Brazen Borrower is their only real answer which is easily handled.
Thassa + Knights are for enchantment based decks and they help against Mono Black Gray Merchant decks.
The counter magic and is for mirror ramp decks, Sultai, and combo decks.
Playtest it, Love it, Upvote it!
