To me, if a two-colour splash deck is stopped dead in its tracks by a
Wasteland just once in an environment that I curated, that's already too much.
Just to be clear, any, say, 3 CMC land destruction spell can do this too. Let's not pretend this is Wasteland specific.
There's something that I think is not being addressed here. Look at the various aggro decks that pass through standard, and a
lot of them are full of very specific interactions. If not tribal, then something like Temur Battle Rage + Become Immense. Or Kudoltha Rebirth. Or whatever.
And the typical Standard control deck is kind of just a pile of cards. Maybe there are some interactions in there, but it's usually some mix of card draft, removal, counterspells and finishers.
It's far more easy to assemble a Constructed-esque control deck than a Constructed-esque aggro deck. I'm never going to explode out of the gates with a Turn 3 aggro kill. It's really not possible.
So by design you have this sort of inequality that nobody wants to talk about, and it's more than just powering down wraths. Just because there's good mana (or good-ish) doesn't put aggro in the upper hand.
I will say that
Wastelands might make more sense for Aoret's unlimited fetches environment, where a player is much less likely to become randomly colour-screwed if their first or second land explodes.
I agree a lot with this point. In my original "learning from legacy" bit, I wanted Wastelands to be something you could play around more. Obviously most of the time you don't get the fetches that perfectly match your colors so that you are free to get whatever basic. Or could get a basic but want to risk getting a non-basic.
I push aggro a bit more than the average 360 (better Turn 1 mana, breaking singleton on a few effects), but I also don't run a lot of the GRBS aggro cards (no Winter Orb, Sulfuric Vortex, Armageddon, etc). People have complained about aggro forever and ever and if you strip away land destruction I don't think aggro is doing so much better in my environment than elsewhere. Even if you push the wraths back a turn there are other T3 and T4 stabilizers.
So the question I would ask is, what knobs do you want to twist? I'm willing to try double shock no dual. I'm willing to try some variant on Wasteland, so long as it can be used on MTGO (ala strip mine errata). Something like:
: Destroy target non-basic. Only activate this ability if your opponent controls
3 or more lands.
Does 3 do it? Tec Edge is a two-color Control card and Wasteland is an aggro card, should we find some actual middle ground? Should Wasteland cost you a mana to activate (that you just have to drain from your pool)? Should it have some
Serra Avenger clause on it? Activate only if your opponent controls lands that tap for 3 or more colors of mana? I'm not going to take the Wastelands out without some more appealing alternative.
