“I summon ‘Royal Gambit’ for 2 White and 1 blue mana. Due to its effect, it does not take summoning sickness. By paying 2 life, I can activate its second effect: I combine all if everyone’s health, divide it by 3, and add that many 1/1 counters to it. You have 10 health, James has 20, and I have 15, making it a 15/15 with flying. I the swing at you for game. After royal gambit attacks , it goes immediately to my graveyard, and I pay as much life as I did damage this turn. I play an instant, for 5 white and 5 blue, that allows me to add poison counters to target player equal to half of their health. I choose James. 20/2=10, so James does by poison, and I win the game. You can not outsmart the queen. Gg”
