Looking at a Random Card: Multani’s Decree
(What am I doing here? Read here!)
Multani’s Decree: It’s not black, and it’s not a creature! What a change!
Unfortunately, there’s not much to say here. This is a Tranquility costing 1 mana more and gaining you some random life. That is, of course, a bad deal – the difference between 3 mana and 4 mana is huge, and if you really gain an impressive amount of life, this spell most likely is such a blowout that the life’s still not important. Yes, it is a tad more interesting in multiplayer (which I don’t care about), but even there you’ll probably prefer Tranquility (well, actually, Back to Nature, but that’s a much newer card). And yes, there is the faintest possibility that you might intend to use it to destroy your own enchantments and gain a lot of life in the process – don’t ask me how, but stuff like Hatching Plans or Rancor-effects might provoke so-called Johnnies to do such a thing IF they care about the lifegain in addition to planning on blowing their own stuff up.
Let’s get real, though: This is a blank in constructed, and most likely in casual, too – even casual players like their basic utility cheaper (or, preferrably, made more attractive by being tacked on a creature like Indrik Stomphowler or something) So, the only interesting question is: Is that a good tool for building limited environments? Actually, it’s okay – an enchantment sweeper costing 4 mana will find its uses. The random lifegain is still random here, though, probably even if the environment specifically cares about lifegain, since a 4 mana sorcery is quite clumsy, and the card quite situational. (Molder, for example, is a better choice for such environments, as are Terashi’s Grasp or Solemn Offering in White.) Because of this, I prefer the cleaner, more basic and classic effect of Tranquility, which isn’t overpowered at all (unless an environment is all about enchantments, but in that case you wouldn’t want to use Multani’s Decree either). Back to Nature, however, is too strong – partly because two mana is really cheap for such an effect, but mostly because instant speed makes it way too easy to wreak havoc against an opponent relying on enchantments in combat.
So, Tranquility is the perfect choice for this very basic and important, but not always needed function, and the Decree is just a little less elegant and a little more unwieldy. The flavor of this card is not helping, connecting a very basic effect to quite a specific context (and I also don’t really get how a decree destroys enchantments and gives you life in the process). This Tranquility variant only has a right to exist if it actually achieves something with its lifegiving ability, which it doesn’t. (Making the lifegain unconditional by giving you a fixed amount of – say – 6 life would have been a solution, encouraging players to maindeck this card, and maybe even care most for its lifegiving ability.) Overall, the card is useful (in limited only), but not needed or wanted at all, and causes no problems – a poster child for a solid D.
