Kiora, the Rising Tide Kiora, the Rising Tide reminds me of Champion of Wits, a card that offers immediate value when entering the battlefield or when blinked
Scar allows all Ally characters to get a +1 strength, and if Scar is exerted at the end of your turn, you could draw cards equal to the challenge strength of one of your Ally character cards, although you must discard two cards and banish that character
Not only that, this card has a good amount of willpower and lore-generating capability too, since each quest gets you three lore, so it can tank some damage and still help you win the game.
The game will try (and fail) to sacrifice Summon: Bahamut each time a player gets priority, but it won't get stuck in an infinite loop
This card fits into Gruul midrange and aggro decks alongside cards like Gruul Spellbreaker, Questing Beast, and Embercleave
