Fat-free cheese is (theoretically) better for you, but it completely negates the purpose of eating cheese by giving you - at best - a mediocre experience and at worse a genuinely unpleasant one. I always respect a given partner's wishes, but... if I knew we were both selective in our choice of partners and she was on birth control or couldn't have kids, I would be greatly in favor of skipping the condoms. It really significantly detracts from sex for me, at that point I usually suggest we just use oral/other third base maneuvers on each other if the condom is a sticking point (har har).
All of this, however, is off-topic from
Mwonvuli Acid-Moss.
Personally I find it a little odd that it is being used in ramp decks, and is mostly a sign of how few options we possess in Duels to legitimately ramp. Drawing land cards is simply not the same as actual ramping, so up until BfZ our options were laughable.
Mwonvuli Acid-Moss is still one of the better options, despite now having other ramp besides
Animist's Awakening, which nobody ran unless they were trying to get the Accelerated Production achievement. Y'see, if we had
Llanowar Elves and
Rampant Growth nobody would be talking about
Mwonvuli Acid-Moss in ramp decks because at the end of the day, it is a control card.
What it does: denies your opponent resources, delays the opponent, accelerates you towards the late game. All of this is control's game plan, which you can see in my Land Control deck post I updated in the Nephilim deck thread. I've been using
Mwonvuli Acid-Moss since 8 o'clock, day one (props if you get that reference)... as a control card alongside
Into the Maw of Hell. The fact it happens to be a solid option for ramp speaks to our limited card pool rather than its "brokenness" as a ramp tool.
I will say that I find its inclusion just a little odd in the base card pool. Surely
Creeping Mold would have been a better generic card to include? I feel it is a bit strong when held against some neighboring cards since it's 2-for-1 and mana acceleration, but probably no worse than if
Mind Rot or
Consult the Necrosages had been in the base set. Really, there are some much crueler green cards that could have made it into Duels, like
Chain of Acid or
Fallow Earth or
Rain of Thorns, or more powerful cards like
Harmonize or
Shard Convergence, or just interesting choices like
Make a Wish or
Summer Bloom. Considering all of that, can you really accuse
Mwonvuli Acid-Moss of being the bad guy? It's doing what a green card advantage card does (as someone mentioned earlier) without breaking the game in half like a
Plow Under would do. There'd be some REAL complaints going around if that card was in Duels.
My prediction is, as new sets join the table and every color gets more of the core effects that define them, in this case green getting more and better ramp effects, you'll see less use over time of the dreaded Acid-Moss as people begin choosing cards that cost less mana to ramp, or that ramp them further such as
Explosive Vegetation. This problem, in other words, is going to fix itself once they introduce better ramp cards into Duels.
But not if you fight my Land Control deck, because that's the point then, even going so far as to consistently regrow
Into the Maw of Hell because you're not allowed to have lands or creatures. ^_~ Acid-Moss is solidly a control card to me, and over time it will drift there as it is meant to do.
