Saying that the game isn't supported on phones is totally wrong as I had a theory after seeing other people here saying that the game works fine on their phones too so, I installed shareit on my ancient tablet which i play the game on and transferred the game to my phone. After downloading the data I played an online match and everything went perfectly except the text size on the cards was so tiny but readable which is something that could easily be optimised for phones by making a magnifying lens icon to read the text better or something like that. The point is the game really works well on phones so please release the restraint on the play store so that when an update comes I could download it on my phone easily, even if you don't make any changes you can release the game the way it is now on phones and say it is a beta for phones to see the problems and fix each problem at as they come so by the end of the year a magnificent card game will be ready for most phones and will be a super successful as there is almost no competition when talking about the extremely high level of complexity and divergence in cards and strategies.
All in all, please please please consider this as the game is so wonderful and it is such a great shame for it to not be on phones and if the game needs really strong internet connction you can put a warning at the start of the game so you won't be responsible if the connection os lost.
Your loyal player
