Haven’t played this game in a couple of months and don’t see her in the planeswalker buy list. I had her down to 20 hp and then whatever crazy combo setup she had, gave her 70 hp and as you can see summoned and pumped her guys up. I watched the screen for 2+ minutes as her combos went off and repeated!
This would be Kiora. She’ll probably be coming out in the store in a few more weeks. This is my assumption based on the release of Koth, Garruk etc.
Kiora is one of only two planeswalkers to have two base colors right now. She can use both blue and green cards - but only gets bonus mana from said colors. She also has a focus on spells, which can make for some fun deck ideas. Based on the screens above, I think that deck features a lot of card draw… as well as cheap spells for a near infinite loop of spell chaining.
