Istantaneo
Pesca X carte e perdi X punti vita, dove X è il valore di mana di un comandante che possiedi sul campo di battaglia o nella zona di comando.
If your commander is under the control of another player as Stinging Study resolves, it is still on the battlefield and will still be used to determine the value of X.
If you own multiple commanders on the battlefield and/or in the command zone, you choose one of them as Stinging Study resolves to determine the value of X.
