Biomass Mutation

A Simic card that's undeniable Simic. You see, when you use an effect like this to change a creature's base stats, any +1/+1 counters on it are counted afterwards. In Ravnica 1.0, some people had some fun with Omnibian, using it like a Polymorph effect on opponents' creatures or a Giant Growth effect on their own. The Simic no longer use 0/0 creatures, but they do still love to pile on the +1/+1 counters, which means Biomass Mutation is worth a lot more potential power.

The fact that it's a potentially game-winning X spell in the color of mana acceleration is a major help as well. I suspect that this is going to deliver more than its fair share of deathblows in the coming two years.

Biomass Mutation

Do you guys remember Eventide? You should look it up if you don't. It was a good set. At the time, though, I was more concerned because it had a high number of "copy" and "become" effects, and since at the time I was the resident rules expert in my group (though far removed from actual rules experts), I was afraid it was going to turn every meeting into a rules session rather than a gaming session. (Just a couple of months earlier, I'd spent most of a meetup explaining why Mutavault plus Mirrorweave beats Cryptic Command or Wrath of God.)

Fortunately, Biomass Mutation is a lot simpler, as long as you remember that auras and +1/+1 counters apply after this card's effect. Since it doesn't target, it's less risky than a lot of creature-boosting spells, and since it's an X spell, it can beat life-gaining decks more readily than something like Overrun. Plus it gives you another excuse to attack with an unenchanted and unequipped Ornithopter or Aven Envoy, and that's just hilarious.

Welcome back readers today’s card of the day is Biomass Mutation an interesting finisher card allowing you to change your creatures into monsters. In standard I could see this card acting as a sort of finisher for token based decks or decks that spew out a ton of small creatures, aside from its obvious uses as a finisher, the creatures keep their abilities making it a more powerful when your creatures have combat centric abilities. In modern the same concept applies make a small army and turn it into a gigantic force. Token support in modern is different meaning this card could see some play the instant speed means you can surprise people in combat with it or save it for the final killing blow. In legacy and vintage its kind of slow. In casual and multiplayer token strategies or infect creatures could make good use of a way to increase their power, the instant speed becomes more relevant to protect yourself. In limited it seems like a mana intensive bomb a heck of a combat trick and a way to put the game away. Overall a powerful card that could see in multiple formats and the kitchen table especially paired with token generation.

Today's card of the day is Biomass Mutation which is an X and two Green or Blue instant that makes creatures you control X/X until end of turn. 

For a 1/1 token deck just four mana can double the power and toughness in play while five or six would triple or quadruple it.  In those situations this is a very efficient card and it also works well with +1/+1 counter decks like Simic as it only changes the often low base stats, not external modifiers.  Overall this is a beneficial card to particular decks that works offensively or defensively, but needs the field to be arranged a bit to be efficient.
In Limited with the frequent endgame excess of mana this can be a big finisher or surprise defensive move, particularly when played alongside Simic's counters.  The hybrid mana allows any deck with Blue or Green to include this and the potential justifies a slot in most Sealed builds. 

In Booster this is a fairly midrange first pick, it can do a bit, but looks for both creatures and a decent supply of mana.  Even with that it can be difficult to pass and it is a solid start to a Simic draft.

Biomass Mutation Card of the Day
John Shultis

Welcome back to Pojo.com's Card of the Day section! We have been looking at green cards all week and figured we should close out with a great one from Gatecrash. Biomass Mutation. Biomass Mutation is a rare hybrid blue and green instant that costs X and two hybrid blue/green mana. Biomass Mutation says until end of turn, your creatures become X/X.

How great of a card is BIomass Mutation? Well, that depends. I have seen it sweep in and spell defeat several times already, when properly used. And even when it isn't even there. What do I mean by that you ask. Well, I'll explain. Once your opponent knows that the potential is there for a Biomass Mutation, it messes with their strategy. The reason is, they won't want to fall victim to it more than once. So, you enter your attack phase, and all your mana is untapped. your opponent will likely choose blocks they normally wouldn't if they didn't know you were playing the Biomass Mutation. Which this itself could all be a bluff, and then still cost them the game because they lose their creatures.
But a deck that is properly designed will win with Biomass Mutation regardless of how your opponent responds. A deck swarming with small fliers, such as a Faerie deck, will gain air advantage, and thus a significant pump, while still allowing to counter spell, will spell certain doom for an unsuspecting opponent. Decks that thrive on Trample and mana ramp, or unblockable creatures will also see the benefits of Biomass Mutation. And the great thing is that this card can run in either or deck style, because of being a hybrid.
