You'll be able to make excellent decks in both blue/green and blue/black. There has been exceptional competition decks in each of these color combinations.
It doesn't matter specially whether or not the colors within deck are allied or enemy colors.
Here are a few what to keep in mind in regards to the two-color combinations:
* Green usually gets larger animals than just about any various other color. Perhaps the green animals that cost 1 or 2 are much better than these are typically in other colors. Green additionally gets mana production. Additionally gets means that make creatures bigger, much more than just about any other color. Green essentially sucks at anything else besides these things.
* Blue gets counterspells (means that cancel some thing since it is becoming cast). Blue in addition gets bounce spells (spells which get back one thing from play to its owner's hand). Blue additionally gets draw means, traveling animals, and other "challenging" things. Blue creatures are smaller in proportions than many other colors' (although blue does get huge fliers), and blue actually good at dealing with things once they've been already played (aside from jumping them).
* Blue and green creatures complement both really, because green features effective ground creatures for the very early game and blue features powerful traveling animals for the late online game. (Most early-game blue creatures tend to be awful compared to other colors' early creatures.)
* Many successful blue/green porches stick to the "aggro/control" strategy: Enjoy some creatures early, and then disrupt your opponent and protect your creatures to enable them to attack for the victory. There is it hard which will make an excellent blue/green deck in virtually any other style.
* Blue and green are the two worst colors at killing animals. Once an animal's on the table, you will likely simply be capable of getting rid of it by killing it in fight or by coming back it to its owner's hand (such as for instance with Unsummon). The card Snakeform from Eventide is one of the best treatment spells previously printed in green or blue, nonetheless it still just works during combat. In the event the adversary plays something like a Royal Assassin (Tap to destroy target tapped creature), after that a blue/green deck is not likely to be able to get reduce it.
* Black has actually pretty good early-game animals (though not as great as green's). Both blue and black will get some good great creatures for the belated online game (huge traveling animals, including).
* Ebony is great at killing non-black creatures. Black additionally gets some methods to destroy other black colored animals. This will be one of the most significant factors people play black colored (especially in informal games).
* Many effective blue/black porches proceed with the "control" strategy: Play countless means to interrupt the adversary (like means that kill creatures and blue means that counter other means), after which win by playing a big, scary, probably-flying creature later on inside online game. You may also make great blue/black porches of various other designs.
* Blue and black will be the two worst colors at the removal of artifacts and enchantments. In either case, a you will be able to do is get back an artifact or enchantment to its owner's hand. (but being bad at the removal of items and enchantments is usually less devastating than being bad at eliminating creatures.)
So in the event you play blue/black or blue/green? I dunno. The truth that blue/green decks can not eliminate animals has a tendency to annoy me, thus I generally speaking favor blue/black. However, you will find merits every single option. Ideally a number of the things I've said makes it possible to to come to a choice.
