Pointed Discussion

Is the Elemental colorless? Probably not but I wonder if it will be errated green and blue or only one color (similar to Call of the Conclave's token).

@Avetenebrae Yup, it would be colorless. If it doesn't explicitly say that it changes colors then it stays what it is, in this case colorless.

Can someone explain to me how this is a good enough card? I mean, really, is turning one of your lands into a creature really that good of an idea(Aside from the manlands, that is self explanatory. I mean cards with this type of ability) ? Assuming you are going to use this new land/creature for combat, (not much else you'd do this for) doesn't that leave you one mana less for this card? and in combat, there is a chance it will be killed.... now you are down a land.

I'm not dissing the card, or the ability, I just want to know how to use this effectively. Looks like a lot of fun, and telling new players that I clonked them in the head with an entire Forest is in itself a reward, but how is this preferable to playing a creature?

Beautiful card. Very Simic. Sad that this doesn't work (I don't think) with evolve, since nothing is entering the battlefield.

It can serve as a surprise blocker that catches flyers and prot. from color evaders. It can get those last points of damage in. You can also use it on your opponent's lands for improvised land destruction (Gruul Charming those Azorius flyers? Snipe a land on the side). Considering how weak LD currently is, that last one might be it's best use :P.
So not obviously powerful, but flexible and sneaky.

Nifty combat trick, but can't be cast if you have mana-producing elves after an Armageddon.

@WannabeJedi1337 Because it's an instant, meaning you get a surprise blocker (or a hasty flier if you prefer). Also if it wasn't obvious, people here are talking about limited.

This card is a trap in Simic. Maybe as a green splash in Izzet?

It's almost a Searing Spear, but with a lot more downside.

Has some potential uses, but alas, does not synergize with basically anything Simic this time around. I suppose it could be hilarious using Bioshift to turn it into a land with a metric ton of +1/+1 counters on it for next time around, but I can't really see any other uses for it.

would this card work with Sever the Bloodline to remove all the lands with the same name from the battlefield?

This is a very pretty card. :)

@ TwistedBobbay: I do not believe that would work, because Sever the Bloodline says: exile target creature and all other creatures that share a name with it. Not lands, I am sorry to say.

Use Cackling Counterpart on this temporary land-creature elemental and then get new permanent colorless 3/3 flying tokens that can tap for mana every turn with your Growing Ranks

I can possibly see this alongside Odric as a 2-drop kill land (Targeting your opponent's land) but that's super conditional, due to the req'd additional 3 attackers. Doesn't really have a place in Simic this time around...

'So, what Creature are you going to pump with Kessig Wolf Run then?'

*insert Xhibit face*

Best use I can think of is that it blocks and kills the limited bomb, Skyknight Legionnaire. No doubt it has other complicated and wonderful uses in legacy, and it's a flavour-tastic tribute to Gaea's Skyfolk. All round great design, even though it's a terrible card for winning games. It's not all about the winning, folks!

Best use right now seems to be as land destruction with targeted hate or something like pinging death touch. Wonder if this would work with progenitor mimic to get you a free land every turn? It would be valid as a target when p. mimic first resolved but not sure after that. "If this creature isn't a token". May have to still be a creature when the ability triggers.

So if you use this then copy with Progenitor Mimic, is that an extra land each turn?

If I used Thespian's Stage to copy the land that was affected by this spell, would my Stage become a 3/3 creature?

@NickDay: Nope! For the most part, the only things that carry over to a copy of a permanent are the characteristics given by the card/token-creating ability that created the thing that's copied, unless there's a copy effect applying to that permanent in which case the characteristics given by that copy effect are used instead, including any modifications given by the copy effect itself. (eg. If you cast Evil Twin and copy a Boros Reckoner, then later have a Progenitor Mimic copy it, the Mimic enters the battlefield as Boros Reckoner that can destroy other Reckoners for and tapping, and which makes a copy of itself each upkeep if not a token.) Hydroform would therefore not make a Thespians's Stage that copies its target be a creature.

@taproot: Yup! Something a little odd would happen, for the reason I gave above. If you have the Progenitor Mimic come in as a copy of a Temple of Mystery that had been Hydroformed, it enters as a noncreature land named Temple of Mystery that comes in tapped, scrys for 1 on ETB, taps for or , and makes a copy of itself each upkeep if it's not a token. Therefore each upkeep you're getting a tapped token Temple of Mystery for free.

It's a mini land destruction...if you have a plummet in your hand. The best this is is a hasty 3 damage for 3 mana.

I like these in standard for killing an oncoming abyssal specter. I feel like it has more utility than simply running plummet since you can use it to attack, and it can block those non flyers too. Real big shame this doesn't trigger evolve though.... Outside of standard i guess its pretty meh.

I want to use this on an opponent's land, as my daring thief is about to untap. Assuming I have a creature to hand them.
