Nice mod thanks. I was wondering if your code was on GitHub as there are a few ideas I'm interested in borrowing. Also, JohnnyBazooka89's StSModdingToolCardImagesCreator might be of use to you if you haven't seen it already. Though maybe you may have some issues with your original images (LoL icons) being too small.

If you ever want to try image scaling Waifu2x works well.

Thanks for the info with the Image tool.
Also i've made the mod public so you can look at the code, hope it helps.

jinx's powpow/fishbones mechanic feels horrible to play with. ignoring balance, fishbones should be more expensive than powpow (of the two in league, fishbones is the only one that actually takes mana after all), but really i think it would feel better if it was closer to The Watcher's stance mechanic, where you play one of several cards that will put you in the stance you want and if you ever want out of that stance you have to play a card that changes you to another or just exits your stance.

also in the short time i tried this mod out, it didn't seem like jinx had anything like the stuff she has in LoR, which i think would be nice.

i don't want to come off as too much of a hater, because this is a very interesting mod. anyway i used the fabricate mod to create more jinx cards, and it became a lot more fun to play as Jinx with these (and also all of the silent's discard cards to make sure there was enough support to make it work). so here's some of what i've got:

in LoR Jinx's champ spell is a 3m fast speed spell called Get Exited, it deals 3 damage and needs to discard a card. I think it'd be kinda weird for a Jinx attack card in this mod to also be called Get Exited, but the image used for that card is one of her monkey bomb thingies so giving it a different flavor wouldn't be too hard. Anyway i turned it into a 1m common attack that deals 8(+3) damage and requires you to discard a card.

another card in LoR that i felt MUST be brought over is called Rummage, it's a 2m burst speed spell that discards up to 2 cards to draw that many. So i turned it into a 1(-1)m common skill that allows you to discard up to 2 cards to draw that many.

those two cards are great additions, but what about cards that want to be discarded? In LoR, there are 2 main ones id say for the discard archetype. The first one i want to bring up is Vision. In LoR, Vision is a 3m burst speed spell that grants all allies +1/+0 and plays itself on discard. Now that would be easy to adapt into StS, but i don't think that's very fun or interesting. So i changed the play effect. Vision is supposed to represent the Noxian virtue that is essentially intelligence, and so i made it give block instead. Anyway Vision became a 2m common (or maybe it'd be better as a uncommon, wasn't sure about that) skill that gives 10(+6) block when played, but gives 1(+1) strength on discard.

the other main card that wants to be discarded is Jury-Rig, in LoR it's a 1m burst speed spell that summons a 1m 1/1. Typically in Jinx decks this is used for a very agro play style, but thanks to the fact that it's burst speed it can also be used to create a chump blocker in a pinch. So i thought it has to have one effect give strength, while the other gives block. While it might be more accurate to LoR to make it give strength on discard instead of block, i feel that it'd be stepping on Vision's toes a little. So, there was only one way for it to go, Jury-Rig became a 1m common skill that gives 1(+1) strength when played, but 5(+3) block on discard.

in LoR there is a card called Funsmith, and i forget if this fun smith has voice lines for when you play Jinx, if Jinx has lines for when you play Funsmith, or both. Eitherway they know eachother, and i feel it'd be kinda criminal to leave the Fun Smith out of this. Funsmith is a 4m 2/3 that has an aura that gives your spells 1 extra damage. Which doesn't translate well into StS. I kinda want this to be a power, but i didn't want it to be a copy of the ironclad's inflame. so i made it a 2(-1)m uncommon power that gives 1(+1) strength plus an addition 1 strength per card discarded this combat.

next up i wanted to add the other discard champions in LoR, since if you are making a jinx deck in LoR you probably are looking at them to be the other 3 champion cards you can put into your deck. I'll start with the OG, Draven. He was released in the foundation, where the only discard deck was Jinx + Draven aggro. In LoR Draven is a 3m 3/3 with quick attack that creates a spinning axe (0m burst spell that discards a card to give a unit +1/+0) in hand on summon and whenever he strikes, so i made him a 1(-1)m rare attack card that deals 8(+3) ranged damage, gives you 1(+1) strength, and you can discard any number of cards for an additional strength.

the next 2 champs came in the same set and were made to go with eachother, but since they both also are about discarding cards you could easily fit either of them into a Jinx deck. In LoR Sion is a kinda expensive card, but when he's discarded he gives an allied unit a buff and shuffles himself back into the deck. Since StS shuffles you discard pile into your draw pile once you deck out there isn't any problem with losing a card forever once you discard it, but i really like the idea of discarding him untill he can become the late game threat LoR want's him to be. So i made him a 3m rare attack that deals 5(+5) damage to all enemies, and when you discard it it gains -1m and +1(+1) damage.

Rumble is a kinda weird champ in LoR, but i kinda wanted to keep his weird discard 3 cards to get 3 very specific buffs. I couldn't figure out how to get it to work in fabricate, so i made him a 3(-1)m rare skill that give 15(+5) block, and lets you discard up to 3 cards for that many strength, artifact, or free attacks.

i think these cards encourage you to play fast and a little loose, which is very in character with jinx. It might not be balanced, but it's fun. I hope you find this interesting, or helpful, or something.
