Interface for casting cards with Kicker through Etali, Primal Storm's triggered ability
During a game of Chromatic Cube, I attacked with Etali, Primal Storm. Its triggered ability exiled the top cards of both libraries : a land from the top of my opponent's library and a Joint Exploration from mine. I had no source of green mana so I wanted to cast Joint Exploration without kicker.
The UI displayed the usual prompt for kicker cards : two options, the first "without" kicker and the second "with kicker". However, only the second option had the blue haze around it that indicates a valid option. Because I was accustomed to select options with the blue haze, I tried repeatedly to select the second option "without kicker" and each time the game prompted me to pay a green mana, so I had to cancel.
Finally I realized I could also select the first option even if it had no blue haze, so the game logic works but the UI is broken or at least very counterintuitive on this matter : both options or only the first one should have had the blue haze. I lost my BO3 because of the clock, but would have won it with 1 or 2 more minutes, so perhaps the time I lost with the UI problem cost me the victory.
