Twin strike said "resolve up to 2 of your blue character dice showing melee damage as unblockable"

Ataru strike said "resolve one of your blue character dice showing melee damage, increasing its value by the number of shields on that character"

I have old man Luke in my deck, and I rolled 2 dice showing 2 shields each, I used to played twin strike as unblockable from Luke's ability shield into melee damage, but my opponent disagreed. There was 8 of us debated about it, 2 disagreed and 6 of us agreed that is legal to play. I reminded them that ataru strike is very similar to twin strike because they're both said "resolve" and "showing melee." One of the guy send the message to the World Champions judge, and he confirmed that is legal. I just want to let everybody know that old man Luke's shields does works with twin strike as well.

Twin Strike uses the word RESOLVE. Luke’s die is considered to be showing melee damage AS YOU RESOLVE IT. Therefore you can use Luke’s ongoing ability to resolve his die showing the shields as melee damage ... So the 6 of you are right!!! Sorry Chad & Conner (I assume that's their names) it hurts to take 4 unblockable to the face!!!

Tho, Luke’s ability only works when his die would be resolved, not when it would be removed.

It's Chris and Mike in AZ, they're still think it's wrong because the cards said showing melee damage and that won't work on old man Luke's shields dice. They don't like the rule on ataru strike, so why not the same with twin strike.

From the Rules Reference Guide page 31:

“Can I play Ataru Strike (z101) or Finishing Strike (b60) and
resolve one of Luke Skywalker’s (a56) dice showing a shield
with it?
• Yes. Ataru Strike and Finishing Strike resolve a die, so you
can use Luke’s ongoing ability to resolve his die showing
a shield as melee damage. Luke’s die is considered to be
showing melee damage as you resolve it. Luke’s ability only
works when his die would be resolved, not when it would
be removed.
Can I play Circle of Shelter (Z107) and resolve one of Luke
Skywalker’s (a56) dice for melee damage?
• Yes. You can resolve his character die with Circle of Shelter
to change the symbol to a shield, then Luke Skywalker’s
ability can change it to a melee symbol.”

FFG has ruled on these types of interactions twice now. If the effect says “resolve” then the dice can be showing whichever of the available symbols. If however it says remove, then it continues to show the original symbol. Thus, while twin strike, Ataru strike, and finishing blow all work on Luke’s dice, Guard and guardian abilities don’t work on his dice. This ruling also makes clear for us that if you have both Phasma3 and Advanced Training, you can resolve dice showing blanks as 1 melee, because you can simply chain link the abilities to change the blank to an indirect, and change the indirect to a melee.

Your friends may dislike the ruling, I know I’ve disliked several rulings myself, but this is an official interaction, not a player ruling, thus it cannot be disagreed with, just disliked.
