Equivalent cards to “Heavy Arbalest” (colorless equipment, grants a tap-to-deal damage effect, but prevents untapping):

• “Viridian Longbow” — Similar tap-to-deal-damage Equipment, but doesn't prevent untapping.
• “Surestrike Trident” — Tap, unattached creature deals damage to player.
• “Power-Arm” — Tap: Deal damage to player, prevents untapping next untap step.

Reason: All are colorless Equipment that grant a tap-to-deal-damage or similar utility, with some restriction on untapping.
