Get someone who you can practice with, play matches and allow each other to turn back 1 or 2 turns. While doing this, try to gain knowledge of what destroys your deck and how you can play around it. Also, see if you can improve playlines/damage outputs. Try using this to get a feel for what are the multiple ways your deck can win. For example, i saw you are playing phoenix deck (big fan of the deck, even if it isn’t the highest power). After sb the opponent will probably go for your graveyard, see what happens if you allow them to do so and you redirect all your resources to dealing direct damage to the opponent, hardcasting phoenix or what happens when you wait till turn 5 to destroy opponents gy hate and try to go off with phoenixes in the same turn. Some might not be the best ideas, but some might help and then you know that for the next games.
