At the beginning of your end step, you may pay . When you do, put a +1/+1 counter on target Shrine for each Shrine you control.
Build a green Shrine-tribal deck that snowballs +1/+1 counters onto your Go-Shintais each end step, then close out games with oversized trampling Shrines or counter-payoff combat. Early turns deploy cheap ramp and Shrine enchantments, mid-game you stack triggers and protect the board, and late-game a single attacker carries lethal damage through.
Cheap two-mana commander that comes online immediately and grows itself plus the rest of your Shrines
Trample built in means your fattened creatures push damage through chump blockers
Mono-green gives access to the format's best ramp, recursion, and big-mana payoffs
Shrines are enchantments, so it slots into a resilient enchantress shell with strong card advantage
Reliant on counters and combat, so board wipes and removal can reset a slow, telegraphed clock
Mono-green struggles to interact with combos and lacks card-draw/removal flexibility of other colors
Only a handful of Shrines exist in green, so the tribal payoff is thinner than the other Go-Shintai colors
Single-target removal on your lone fattened attacker stalls the whole plan
