You start this game with 3 cards of your choice in hand.
Your opponent starts with 0 cards in their hand.
Both libraries do not contain any other useful cards.
What is the highest life total you can end your turn at?
Assume you start at 20 life points. Beyond that, the rules can follow any of the official two-player formats by Wizard of the Coast.
Extra Challenge: If you want a personal challenge (although this is not what I am looking for in the answers to this question), try to find the 4-card infinite-life combo that made me restrict the puzzle to 3 cards only.
