When holding a battlefield with Shen, Leader of the Kinkou Order who has 1 other unit present at the battlefield and 3 Trinity Forces equipped to the other unit. How many points do you score during the beginning phase?

You score 5 points total.

Breakdown: 1 point from the base Hold (Rule 469.2/471), 1 point from Shen's own trigger, and 3 points from the three Trinity Forces.

• Shen's "When I hold, if there is exactly one other unit you control here" is satisfied — the other unit is the only other unit present (the equipped Trinity Forces are Gear, not units), so Shen scores 1 point.
• Each Trinity Force appends "When I hold, score 1 point" to that unit's text, and identical triggers stack (RiftJudge FAQ #520), so 3 Trinity Forces = 3 points.
• Rule 470's once-per-battlefield scoring limit applies only to the Conquer/Hold methods, not to these triggered point-gaining abilities.

Total: 1 + 1 + 3 = 5 points during the Beginning Phase.
