Can using the first ability cause the second ability to trigger?

Yes. If the upgraded character defends and would take an even amount of attack damage, instead it takes no attack damage. That causes the second ability to trigger. You usually get only one use out of the Emergency Defense Field.

If a card with a 'When this battles' trigger (e.g.: Emergency Defense Field) is played on a character after the attacker is declared, will the "When this battles' ability work?
The trigger for all "when this attacks/defends/battles" is at the same time and happens only once as the attacker is declared and tapped. If you use a "when this battles" trigger on a character to then play a "when this battles" upgrade onto that character, the upgrade won't trigger as it's now too late in the attack for those effects to trigger.

Can I have more than one of the same Upgrade on the battlefield?

Yes. Upgrades aren’t unique. You could have two characters each with the same Weapon, for
example.

Some Upgrades say "Put on [something] only." How does that work?

These abilities describe what kind of character the Upgrade can be put on. This is usually a trait such
as Melee, Plane, or Insecticon. An Upgrade can be put on a character only if that character matches the
listed requirement.

Let’s say I have an Upgrade that says "Put on Planes only" and I put it on a Plane. But then next turn I
flip the Plane to its other mode, and it’s no longer a Plane. What happens?


The Upgrade stays with the character it’s on. That ability limits only what the Upgrade can initially be
put on. Once that happens, the Upgrade doesn’t check again.
