Alqust Proft, Master Sleuth
The end of turn trigger doesn’t work as written on the card.
At the end of your turn: Your creatures get +1/+1 for each Simple support you control.
What actually happens is that your creatures get +1/+1 for each new Simple support you control. The card tracks which Simple supports you control, and only gives you +1/+1 for each support only once.
example:
turn 1 you have supports A,B,C
creature X gets +3/+3.
- expected behaviour
turn 2 you have supports A,B,C,D
creature X gets +1/+1
creature Y gets +4/+4
- expected behavior is that both creatures get +4/+4
turn 3 you have supports C,D
creature X gets no bonus
creature Y gets no bonus
- expected behavior is that both creatures get +2/+2
