does the move trigger resolve first before "when i attack or defend" trigger?

Yes, "When I move" triggers resolve completely before a showdown (combat) begins, and therefore before any "When I attack" or "When I defend" triggers are placed on the chain.

According to RiftJudge FAQ #6540:

• Sequence:
  1. Declare move to battlefield.
  2. "When I move" triggers go on the chain.
  3. Players may respond to these triggers.
  4. "When I move" triggers resolve completely.
  5. Showdown/combat begins.
  6. "When I attack" and "When I defend" triggers are then placed on the chain.

Key Timing Nuances:

• No Showdown during Move Triggers: A showdown can only begin during the cleanup step if there is no existing chain (Rule 340). Because "When I move" triggers create a chain, the combat cannot start until that chain is empty and resolved.
• Designations: Units do not gain their "Attacker" or "Defender" designations until the showdown officially begins, which happens after the "When I move" chain has finished resolving.
• Interaction: If a unit is removed or destroyed by a reaction during the "When I move" chain, it will not be present to participate in the upcoming combat.
