I like Fire//Ice a reasonable amount. Still good today. The split cards have always reminded me of the little boxes of one-bowl of cereal that we used to take with us when we went camping. Just a couple of smol magic cards.
Crypt Rats can benefit from both (though not at the same time, since this card won't let you) keywords and sometimes even from the toughness boost. I don't think this is the best source for either, but at just one mana, it might be the cheapest one if you've got a lot of card generation.
Semi-efficient value creature that carries equipment well. If Baleful Strix is the comparison point for this kind of creature, the Imp lags behind, but he's still a better rate than something like Gravedigger (tribal synergies aside.) Pit Keeper is quite a bit too unreliable even if it's 2cmc, so for Raise Dead + Body, Imp might be a solid choice.
Pretty efficient, if kind of unimpactful. Used to think Blessed Orator was great, but we've come a long way, haven't we? I still try to make Hold the Gates decks work from time to time in Commander. I'd like to see a functional Castle reprint at two mana.
Sill one of the cheapest unrestricted discard outlets out there. Compare this to One With Nothing. Dredge decks use the imp to this day, and I wouldn't be surprised to see him if you're playing a few Madness cards. On top of that, a 2/2 that can't block is good for 1 mana.
Fanatic of Mogis is kind of like Grey Merchant of Asphodel, but I see it played much less often. Just goes to show how good lifegain tacked on to something that can actually win you a game can be, I suppose. Also, heavy red devotion cards like Seismic Assault don't really play well into the Devotion->Damage strategy like Necropotence can. A lot of the better red-pip-heavy cards are creatures rather than sticky permanents; and recurring this thing in red is laughable compared to Animate dead and things black gets. Still nice that it hits each opponent, not a bad card by any means.
While better than your average Keldon Champion due to hexproof, elves definitely have better payoffs for having a ton of them in play. I'd suggest either Dungrove Elder for your going-tall hexproofy green strategies, or Alpha Status for elves that want to beat in with one creature (Auras like this are generally bad, but the psuedo-haste you get from being able to attack right away can be underestimated when you're getting lethal-levels of pump)
Why play Elite Vanguard when you can have Youthful Knight? Clearly the knight is better, he has first strike!
Gaining your opponent a small amount of life in exchange for one less mana spent is a good deal a lot of the time, though Naturalize comes out on top against Chalice of the Void X=1. Return to Nature kind of turns Naturalize into a coaster in a way that Claim can't necessarily do, though, because it does the exact same job, but better.
Despite scaling up in multiplayer, not the kind of card you typically want to run in multiplayer. If you want this effect, I'd suggest Exsanguinate before this, or just abandon the lifegain altogether for Torment of Hailfire.
Even after all these years it can still be very large and evasive. Probably better to use Lashwrithe or Korlash, Heir to Blackblade even if they don't have evasion built into them. Nightmare is notably not as bad as Dakmor Sorceress. Remember inverse power creep? Good times.
