If you can send the link to Magic Set Editor afterwards, yes.
(EARTH/Warrior/Effect/Level 5/ATK 2100/DEF 1600)
Once per turn, you can either: Target 1 monster you control; equip this card to that target, OR: Unequip this card and Special Summon it. A monster equipped with this card gains 300 ATK x the level of equipped monster, also if the equipped monster would be destroyed by battle or card effect, destroy this card instead.
If only your opponent controls an monster, you can special summon this card (from your hand).
This is what I thought of if you want a card table
By the way, I meant to mention for Arms Duels that there is a summoning method called Arms Summoning, here's the written lore for Arms Effect
During your main phase the turn you normal/special summon a monster: You can equip this card from your hand or field to that monster in addition to your normal/special summon (you can only gain this effect once per turn). A monster equipped with this card [...], also if the equipped monster would be destroyed by battle or card effect, destroy this card instead.
Also, can you send me the link for Magic Set Editor once its updated please.
I have questions regarding that; wouldn't be easier if there are Arms Monsters? Like Warrior/Arms/Effect. I would be easier for coding in both MSE (which I might make it personally on the S10 frame, as it is easier for me to handle) and CardTable. But that implies being used in Arms Duels.
Also, Spells/Traps? Do they look like the ordinary ones or they are military green? Never heard of it.
And permission to add your example to see how things work on CardTable thus far?
Ok. Also, when do I expect your friend uploads the Arms Duels Card Style HQ yet, if so, can you send the link for the Magic Set Editor with the upload. Also, I might keep my cards outside posting on the internet just in case and make a fanfic out of idea.
