I can't help but groan at how much this isn't a combo with Reckless Wurm. ;)

I was thinking of maybe going "discard a creature or planeswalker" but I wasn't sure if that'd be too pushed.

Oh, ha. I completely missed the part where you have to discard a land... I presumed it was any card. Well, that's a double non-combo with Reckless Wurm then, I guess. ;)

To be honest, it's really, really hard to balance fast mana. You think the restrictions are fine, but then some 'best deck' comes along and just gets a midge faster, and suddenly 70% of the environment is running that deck. I gotta admit that burning a land is a good way to make up for the immediate speed. Here's hoping this spell doesn't let you win by turn two on the play 50% of the time when you do it, though.

The really frustrating thing is that, except for those 'best decks', fast mana is usually bad. Lotus Petal for a round one Black Knight simply isn't a great play. I think you're on the right track for a fun card for a personal set. I'm guessing real world playtesting would tell us that this card is about as powerful as Chrome Mox, which is pretty damn potent.

I think I get what you're saying simply because, even with discarding a land, it is an easy 3 mana on turn 1. Probably would be OP in standard but would be a little more comparable to something in vintage or modern.

I could lower it to , but then it might be not worth it.

Now this sort of just feels like a "bad card" too. But much like Ritual of Flame, it's a "bad card" that becomes a "good card" from a combo and Johnny angle.

I do have mixed feelings about these two cards.
