A lot of new tech is not as efficient or equally so at the get go. Learning how to properly implement and utilize it is part of the process.
Right now we are just throwing raw computing power in ML format at it. As soon as it catches and shows a little promise in an area we can focus and refine. Sometimes you need to use the shotgun to see the rabbits ya know?
This is a wild turn one combo that will win if both players have the same starting life. Assume 20 life each, you play the first card to give you 3 green mana, you play the second card using 2 green mana. This card let’s you use 19 of your life for mana leaving you at 1 life and 19 manager + 1 from the previous card. You play the third card which gives you one red mana (totals are 20 green, 1 red) and finally now you can use the last card by paying one red and X (X can be any number you choose as long as you can pay it). In this case X is going to be 20, for the 20 green you had dealing a perfect 20 damage to the other player leaving them at 0 life and yourself at 1 life.
This combo works for whatever life total as long as yours is greater than or equal to Theirs
