Very tentative idea for the Rampant Growth effect for this set. Not sure if it's too good: getting an Explosive Vegetation for 2 mana is quite a benefit, and people often play artifacts on the first 2-3 turns.

Changed so that the second, bonus, basic land goes into your hand. Which means it can be Cultivate/Kodama's Reach for one mana cheaper, which is still pretty good, but not excessive.

Still unsure about obsoleting Rampant Growth. Considering making this 2G and having the bonus land go onto the battlefield. That way it's Exploding Vegetables for 1 mana cheaper if you get the bonus, and Rampant Growth for 1 more expensive if you don't.

I'm not sure, I think either is probably fine.

Swapping this to be Lay of the Land if they don't have an artifact, and Kodama's Reach if they do.

And if you don't, the library isn't shuffled. Ooops :)

This is now strictly worse than Cultivate. I mean, Cultivate / Kodama's Reach is one of the best land-search spells of all time, so it's not implausible to print something conditionally worse than it, but it does feel slightly bad.

I was trying to work out what bugged me about this. My analysis of deck-building is really untutored, so I'm really unsure about it, but I think the question is, when am I actually going to play this card? Do you have an idea of what function it's intended to fulfil? (I'm really vague about that sort of thing.)

I like the idea of something depending whether your opponent played an artifact in the first 2-3 turns: it keeps you both on your toes as you wonder, and they don't necessarily just run all their cheap artifacts out on turn 1.

But it feels like this may be just very random if it works or not, and feel frustrating if you really need both extra lands, and aren't sure whether to grit your teeth and play a 3-mana Lay of the Land, or hope your opponent may play an artifact next turn.

Conversely, is it supposed to be a hoser to keep "artifact" decks in check? I'm not sure whether it works in that role or not, since it seems like it's only really useful in a deck which wants to ramp up to 6 mana anyway (since Cultivate is awesome, but may be a bit superfluous if you only have 1 or 2 spells costing 6 mana in your deck to start with)? OTOH, I guess all hosers fit into some deck types better than others.

One possibility would be to adjust the mana cost instead of the effect (a 3G Cultivate that you can play for 1G if your opponent plays an artifact). Another would be to reduce the effect slightly (eg. two lands of the same type) and hope you can recost it so it's not strictly better or worse than any existing cards (even if it should be less good than cultivate overall). Another would be to decrease the cost on the base versions or alter the effects so it's at least a bit playable without the boost. (Eg. a 1-CMC or 2-CMC lay of the land that can optionally be a 3-CMC cultivate if your opponent controls an artifact, or a 3-CMC rampant growth that turns into Cultivate or Cultivate+)[1]

[1] I'm not sure if that's a good idea or not. Some hosers are compeltely unusable without their condition (eg. Celestial Purge) whereas others are weaker-than-average but still affect the battlefield (eg. Mold Adder).

I'm going to play this card: As soon as I have 3 mana.

I'm never going to wait for the boost; it's just a nice extra punch in the face for anyone playing artifacts against a green mana acceleration deck.

How it's inteneded? No idea.

Thanks all for the thoughts. Based on the comments above, I decided to make it no longer a mild hoser and more something under your own control. After all, in this set green mostly likes artifacts (just not flyers). This is more likely to be a full Cultivate now, but it's still not strictly better than Cultivate.
