(1) When you Tribute Summon this card by Tributing at least 1 roid monster, remove from play all Spell and Trap Cards on the field.
The (1) Trigger Effect is mandatory, it activates & resolves on the field.
This effect activates in the Summon response timing (like Trap Hole).
This effect banishes ALL Spell / Trap Cards on the field. They are banished face-up.
The Spell and Trap Cards are removed face-up.
Tributing a face-down "roid" monster will count toward activating the effect of "Armoroid".
