A life counter for Two-Headed Giant, a Magic card game where two friends form a team and share one life total. Each team starts at 30 life. Tap the green + to add life and the red − to take it away. The +5 / −5 and +10 / −10 buttons jump by five or ten. Type a number in the box and tap its green + or red − to change that team's life by that amount. ☄️ Snap cuts every team in half. A team is out at 0 life or 15 poison. The speaker button turns sounds on or off.
