I looked at your other KOTOR cards. Bastila is the best, for the simple reason that it is possible to summon her before you die. While I think that most of the abilities are great (after reading all the 'Main Party' cards, Im sold that its a good power to have) I think the mana costs are too prohibitive and too excessive. Unless you have some ridiculous mana-making cards up your sleeve, your just never going to get the chance to play HK or the Exile, which is sad because I liked them
Basically, all Im saying is I think you can make stronger cards that cost less mana and its still ok 'balance-wise'. And if someone says its not, attack them with Darth Revan and you'll find they suddenly fall silent due to a bad case of being dead.
4) Revan's REAL strength is in his command of the Force, which you can represent through any number of insane abilities. He's cited as Charismatic, so a 2UU: Gain control of target Jedi creature would be fitting, He's downright lethal so BB, tap: destroy target creature blocking Darth Revan is not out of the question either, and would allow him to just plain kill any big fatty monsters like Rancors. (it also gives you an interesting puzzle- how to get him untapped to use it. Revan was a tactical genius and his card should require some thought to use)/5 Also, R: deal 3 damage to target creature for Force Lightning just seems obvious.
However, those Force powers are all suggestions, and there's really infinite possibilities you could use for keyword abilities and other abilities to ramp up the power of a 'mere' 6/5 or whatever into a true Dark Lord of the Sith. But definitely change the mana cost to be castable, no more than 6 total, and use at least 1 black and 1 red symbol.
Going in a really unique direction, you could screw around with the Planeswalker rules and give Jedi and Sith 'Force Points' instead of 'Loyalty Counters' to represent how Dark/Light they are, and the powers move them further along that path. Maybe instead of a starting loyalty the just have a Toughness? I'm just throwing a bunch of ideas out there.
Either way, you actually went ahead and posted a card, and Im just blowing smoke, so feel free to ignore me until I have my version up. If I ever actually make one. And when I do, I'll have to give you the credit for inspiring to me to do it. This is a very awesome concept either way and Im glad you posted even if I thought it could also be better
I'm a major Darth Revan fan (after reading the entire wikipedia history of the Star Wars universe, he's STILL my favorite character, because he feels like 'Vader done right' if you know what I mean) so PROPS for this idea. So, I definitely want to see a Darth Revan card, but I want one I can actually use. This card is all wrong by normal Magic design standards-
1) it only costs a single colored mana, suggesting a not very strong alignment, merely a preference. Darth Revan CHANGED his allegiance quite a few times, but at each stage he was a powerfully devout follower of his chosen doctrine. He should have 2 colored mana symbols.
2) Choosing WHAT colors he is is much harder. I think that his character is complex enough to warrant 5 colors, BUT representing his entire being, the full spectrum of his character, on a single card is just awkward, and depicting each stage on a different card is the bester way. This one is clearly his evil Sith mode. Sith? come on. Red/Black all the way.
3) Next, I think that power and toughness aren't necessarily direct representations of combat effectiveness. They're more like just physical stats, which is similar but not the same. Reduce those down to above-average-human levels, but below-enraged-Hulk levels, and you can give him a lower mana cost and actually get to play him. How about...5/6? or 4/7? I could even see 6/6, but that's pushing it. Any more, and he'd look all freakish like he was on steroids.
