If an effect puts a Weapon directly onto the battlefield without playing it, can I put Master Sword on a character that didn't have a Weapon?

Yes. As long as you're not playing Master Sword, its first ability won't apply.

If one of my characters has an Armor or Utility in its Weapon slot, can I play Master Sword to upgrade that character?

No. In order to play Master Sword, it must replace a Weapon in that slot.

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.

Notes from JediPapa:
"Really liking this deck. Super easy to combine with the Stock-Pyl/Nancy combo. Maybe consdier pulling out the Master Swords for something else, they were barely played. Otherwise deck performed well in testing."
