Introducing an old friend; Primal Cocoon! This common Aura can boost up your weakest link on the field into your game changer. The best part; it's only one green mana!
Primal Cocoon can be used in a variety of ways. It can be used to ramp up your weak 1/1 creatures, or build up your all-ready huge ones. Another way to harvest the full potential of Primal Cocoon is to use it on creatures with flying or trample; this way, your victory will come even closer.
Strategies and game play:
You really want to set up your defenses first, because Primal Cocoon is really a gamble. Even though it places important counters onto your creatures, it works at a relatively slow pace; only every upkeep. It even limits the enchanted creature's movement. You really want to secure the battlefield before you consider playing it.
Combos with other cards:
Although the enchanted creature can't attack or block, other cards can work around it. Cards such as Prey Upon deals damage equal to one creature's power to another, and vice versa. The catch is that fighting creatures neither attack nor block, so Primal cocoon won't be destroyed as a result. Cards with the Proliferate effect can be used to halve the time it takes to maximize it's power.
Ways to counteract it:
The standard way of dealing with Primal Cocoon is to counter it, but there is more than one way. Cards like Naturalize can be used to completely nullify it. Creatures with Infect can essentially cancel out the counters, but only if you manage to make contact( aka; have it block or attack you).
Primal Cocoon can be a lifesaver if drawn at the right time. It is a common and can be played for one green mana. The counters it gives out easily pile up.
Its downsides are that its effect occurs only every upkeep, it restricts the enchanted creature's options, and it can be countered or removed.
I am aware of only the version sold in the M11 Core Set, but I hope that it becomes available in a legal set soon.
Artwork and aesthetics:
The artwork is okay, I guess.Mr. Ljunggren seems to be an artist who draws relevant to the card effect itself, but I think that it could have been executed a little more....spontaneously?
Overall, I give Primal Cocoon an 8.5 out of 10; partially because of its drawbacks, and also because it's just so counter-able .
