all possible strategies for playing as Inferno against the Elves.

If you want to focus on Darkness and have a strong Mind skill, you'll have to sacrifice some of the other skills. Sariza's club ignores resistance, so you'll be able to use Mind Control. (if you have it). And what path did the Elf choose? Chaos or Light? This also matters a lot. To prevent the enemy units from reaching you in the first turn, try taking 2 Necromancers, as mentioned above. It's a shame that the Hero is so weak. If he had the "Tactics" skill, it would nullify one more tile, making it easier. But if you have an instant summon, that's good. Given these conditions (having Sariza's club and being confident that the enemy won't reach you with all their units in the first turn), I would cast Mass Dispel (to eliminate Druids and Archers), then, since the Hero will only be affected by 50% of the spell, cast Mind Control (or, if the enemy makes a mistake and moves forward, cast Slow). Then, use Mind Control on the Rakshasa. Use those creatures that only attack and don't cast spells (I don't remember their exact name) because they will tear through those thousands of small creatures with their swords. Your priority is the Archers. Because in one turn (and they usually get lucky), they can eliminate one unit. If you leave them unattended, you've basically lost. So, either cast spells on them, block them with summoned creatures, or prevent them from shooting. (This is just my opinion.) (Please share the replay, I'm very interested in seeing it. (Because I've never seen anything like this before. Usually, my peak level is 20-23).)
