Ive been working on yugioh conversions and have 387 cards about 80% done, just need to find artwork which would be from the original yugioh tcg cards themselves for simplicity, and that I liked it's sake.
izzet has a fair chunk of direct damage to creatures though?
Beacon bolt: 1UR Sorcery from Guilds of Ravnica which is fairly recent
Beacon Bolt deals damage to target creature equal to the total number of instant and sorcery cards you own in exile and in your graveyard.
Jump-start (You may cast this card from your graveyard by discarding a card in addition to paying its other costs. Then exile this card.)
Blast of Genius 4UR from Dragon's Maze Sorcery
Choose any target. Draw three cards, then discard a card. Blast of Genius deals damage equal to the discarded card's converted mana cost to that permanent or player. (also has something to do with discarding)
also there's more than 10 other izzet cards that deal direct damage in some way, also the discard could be a form of overload, just the editor didnt like it when i put it there for whatever reason so i made it an optional cost
edit : if anything its a slight bend in my opinion, as izzet doesn not have any board wipes, also making it mono red didnt seem right either, as there's no mono red cards with optional additional effects. they all are required additional costs, adding blue makes it seem more like an engineered effect to me with izzet wizards messing with something until it got bigger.
fantana: Maybe "Discard any number of cards from your hand, then ~ deals that much damage to each creature and you draw that many cards." It already costs 5 for a boardwipe so it's ok that you draw after discarding. If you want it to say "creatures your opponents control" i suggest: "Draw three cards, then discard any number of cards. ~ deals that much damage to each creature your opponents control." or maybe draw just 2 instead of 3.
That would be because the damage is the red aspect of the Izzet card.
In order for a card to be multicolour, the card's effects have to make sense in both colours. This is why Electrickery is monored and not Izzet.
What you have here doesn't have any effect that makes sense in blue.
fantana, there are two kinds of multi-colored cards in Magic. You have hybrid cards like Vexing Shusher, which can be cast as a purely red card, a purely green card, or anything in-between. Those cards have to have effects that are OK for both of those colors - you couldn't have a card that costed that dealt damage to a creature, for example, because you could cast that spell for and Blue doesn't get to deal damage.
Gold cards, on the other hand, are cards like your Lightning Vortex, which cost mana of two or more colors. Those cards need to justify being multiple colors, so they generally have effects drawing from two different colors. Take Blast of Genius, for example - the card draw is blue and the damage is red. Sometimes there will be effects that only show up in combinations of colors - cards that care about the number of instants and sorceries in your graveyard and exile only show up on cards that are both red and blue, which is why Beacon Bolt is multicolored.
Lightning Vortex is crazily overcosted the way you currently have it - compare it to Fight with Fire. It has the same base effect (deal 5 damage to a creature) for roughly half the cost ( and are roughly the same in terms of how difficult they are to cast), has an arguably better kicker (the kinds of decks that would run something like this are probably going to want the option to deal 10 damage to their opponent's face or wipe out a planeswalker instead of a really hard to cast sweeper), and is uncommon instead of rare.
Lightning Vortex is also a very Red card. Why do you want it to be Blue and Red? That just makes it harder to cast for no good reason.
My personal two cents is that trying to convert cards from one game to another is not a good idea, unless you understand both games really well. Due to the core rules of both games, effects that are really strong in one game can be really weak in the other one.
For example, Graceful Charity is effectively banned in Yugioh because it's really strong. In Magic, "draw three cards then discard two cards" at Sorcery speed would probably cost , at common. This is because Yugioh doesn't have a limit on the number of Spells or Traps you can play each turn, while Magic effectively does (because cards cost mana to play), so card draw is a safer effect.
If you're just starting off with Magic design, stick to the color pie. Going into designing Magic cards thinking "I'll just ignore the color pie if I want to" is like learning to write in a new language and going "I'll just ignore grammar when I want to" - it's a recipe for doing a crappy job.
I'm leaving the forums for a bit because of school. See everyone in January.
didnt think it was breaking the pie. it seemed izzet to me because izzet seems like a volatile color pair based on some cards, but im the only one that thought that way i guess. also i decided just to get help from discord the card is now rakdos-ish
i want to convert them for a custom commander cube, so they are going to get done regardless of whether its a good idea or not. though i'm likely not going to bother putting em here as discord felt more helpful in balancing out the few i threw there. thanks for the suggestions.
