mono-duo decks VS rainbows

[crystalmakwer]

I think there are not many mono-decks that compete with rainbows. My thought is that cards like supernovas give a lot of speed to play different color's creatures in the same turn. I'm thinking about other types of pillar to accelerate mono decks...or strong creatures that dies when in their side of the field there are other different color's creatures.
This is my opinion!

Monos and, to a lesser extent, duos can specialize on one thing. For example, say you want to beat shrieker rush. The best deck to choose would be one with 6 wings or 6 dimensional shields. Of course, that would be nearly impossible for a rainbow because it is too expensive. In this case you would use a mono or duo.

Rainbows, however, are great when you do not know what your opponent will bring. You might want PC incase they have strong permanents, damage based CC (lightning, shockwave) if they have low HP creatures, stall based CC (basilisk blood, freeze) if they have high HP creatures, etc. Rainbows can use a lot of different cards to make them a good matchup against almost anything.

So to conclude,
Monos and duos can counter certain decks very well
Rainbows have a good matchup against most decks, but counter fewer things

Seemingly rainbows have it easier when it comes to quantum production, but they also miss out on using large-cost creatures. Generally, they are balanced.

They also both have weaknesses that don't both the other as much. For example: Mono's or duo's discord is very disruptive, rainbows don't really care. Black hole, annoying to mono and duo, very powerful against rainbow. Rainbows wont be chaining d-shields, but they can chain all different types of creatures. Rainbows also can run into trouble because their is a little bit more luck involve (though the best decks plan around that and run into that a lot less often).
