Trample
At the beginning of your end step, you may pay {1}. When you do, put a +1/+1 counter on target Shrine for each Shrine you control.
Count the number of Shrines you control as the reflexive triggered ability resolves to determine how many +1/+1 counters to put on the target Shrine.
Go-Shintai of Boundless Vigor's reflexive triggered ability may target a Shrine which isn't currently a creature.
