See Ophidian Dreams for what's going on. I like these two cards as instants. Giving your opponent tree cards is most often much worse than the second effect, but if you time it right, the second effect could be crushing, and your opponent has to give you three cards.

Hm. Nice reasoning, but the particular effect is unfortunate because it's untargeted. I'm guessing this is because the rules of "[Player] chooses one" are such that the opponent has to choose before you announce where the damage goes, so it'd be confusing to have it be targeted, but it's still a sadly odd templating. How about "~ deals 1 damage to that opponent and each creature he or she controls"?

Yeah, that would be the reason. I do admit, I don't like the fact that a player can let his opponent deal three damage, only to find that his hexproofed creature can be hit. While I like the idea of a direct damage spell that happens to be the exception to the rule, it probably shouldn't do anything more unique than Incinerate.

Unfortunately, Simoon is probably too unreliable to add to this card. The point is that the effect has to be useful in most games, otherwise, the draw three cards effect will rarely go off. You really need a potential blow-out moment on the second option, that would happen in most games. I'd offer to make this card deal 4 damage to a target, but then we'd be mysteriously close to Browbeat.

How about "Attacking creatures get +3/+0 until end of turn."? It's also situational, but you can build your deck around that effect.

It's an unusual template, but can it be like Fatal Lore; change "target opponent" to "choose an opponent", add an m-dash, and it becomes a modal spell, and then the targets can be chosen by you after the opponent chooses the mode?

A chosen chooser chooses; To choose which way that he loses...

I am totally adding your comment to the flavor text, Vitenka...

Happened to notice this card wasn't changed, yet, to a more appropriate effect. Fixed that.
