Splexit: Explaining 0-Colour Start

'ey. Myrmiredon here. Head Dev of BLOX Cards.
You might've noticed that all of your colored icons have disappeared when you start a match. Normally, when an update happens, I explain what and why these changes have been made in the discord server.
However, this update is a special change that radically altered the game. I want to make what's going on clear for as many people as possible. If you're just here for the changelog, it's at the bottom of this page.
From 3/30/19 to 4/27/19, we tested an experimental change to the game where we start with 0 colored icons - only four white. It had shown extreme promise in private tests as to fixing several problems us developers have had with this game. This change worked as intended, so we kept this change.
It's been quite emotive for some people, and this page is explaining what's going on.
What problems did 0-color start fix?
== Problem 1: The Splashing ==
BLOX Cards is a card game. Card games tend to be more fun the more variety of cards see play. One of the tools we use to increase card variety is to separate them into four colors: Red, Green, Blue, and Yellow. This stops all the best cards being played in one deck. In addition, more powerful cards cost more. Altering the cost of a card is the best tool we have to balance and design the game, and it's very important that that tool is kept useful.
In the old system, we started with two of every colored icon. This led to a technique known as "splashing"; playing a small amount of off-color cards in your deck. Because you start with two of every icon, these small off-color cards are essentially free, which leads to a whole host of problems.
Imagine that I showed you a card that costed NNMM - two of one color, and two of another, such as JavierCollin88Poppin. It would be intuitive to think that this should be stronger than a card that costs just NN - two of a given color. Thanks to splashing, this isn't true - in a deck that doesn't play red or yellow icons, JavierCollin88Poppin costs nothing.
Because JavierCollin88Poppin simultaneously costs 0 and 4 icons, it becomes very difficult to give him appropriate stats - If we balance him around the fact that he costs 4 icons, green and blue decks can play him for free as a huge beater. If we balance him around the fact that he costs 0 icons, then the red/yellow decks he's intended to be played in can't use him.
Splashing also means that powerful low-cost cards can be played in any deck. Arte71 is a very powerful, yet balanced card at WWBB in blue decks, but in non-blue decks you spend WW for a 300/300 that also has one of the strongest effects in the entire game. As a result, Arte71 has had to cost three blue and is a less fun or powerful card because of it.
The most extreme example is Clockwork. Clockwork costs 10 icons, but can be played as if he only costed four - He sees the most use in monoblue. How do you begin to balance that appropriately?
The icon system in Blox Cards heavily incentivises playing one color. As a result, we place in tools that enable two-color play (such as Mickymack) and we also put in rewards for playing lots of colors (such as Satyr Firemaster). Splashing makes multicolor play harder because these tools have to be severely weakened in power so that off-color decks can't abuse them. As a result, monocolor dominates.
== Problem 2: The Speed ==
One of the barometers we use for how healthy the game is is how much you need to have a board state on the first turn. Can you take a turn off to play support cards like an acolyte? 2-color decks, control decks, and archetype decks tend to be slower than the average midrange/good stuff deck, and those decks need time to set up their own board.
Under the old splashing system, so many cards could be splashed that you had incredibly explosive turn-1 starts, taking full advantage of your splashes. You were forced to answer this on the first turn or immediately lose. 
The hope is that, by taking splashes out of the game, we severely cripple the ability of decks to play on the first turn without discarding, allowing these slower decks to have a fighting chance. 
== Q&A ==
I'm going to address some likely criticisms here. As a game designer, your feedback is very important. 
"Those multicolored decks needed those two icons to begin with. Now I can't play multicolor."
It is true that this update punishes multicolor decks by removing their ability to start the game on two icons. Rainbow decks in particular struggle immensely. However, thanks to splashing being gone, we're now allowed to freely push cheap multicolored cards. Check the change log for more details.
"Won't this just make monowhite really powerful?"
Yes. If nothing was changed, monowhite would become a highly dominant deck. This was anticipated; We've chucked colored icons onto the deck's largest hitters, forcing players who want to use monowhite to build a dedicated color base.
"Won't this break the tutorial/AIs?"
Yes. Because this is a two-week-long test, we have decided that fixing the tutorial and the AI is too much work for not enough gain. It's the number one priority should this test become a permanent staple; please do not let it cloud your opinion.
"You broke my deck!"
During private tests, we've found that after turn five, most decks operate the exact same. The ones that don't are ones that require a splashed card (Skeleton Armada control) and degenerate rainbow decks that exploit how splashing works in the first place. If you feel your deck is a broke from this, swap out 2-4 cards for all-white icon gen. It should fix itself naturally.
"Now I have to play tons of white-costing cards!"
Under the old system, many cards have single icon costs tacked onto them in order to make them icon neutral. They don't "net" an icon without surviving a full turn. We're looking into this; these cards should be a lot safer if they cost all-white now, although they may take a small nerf in exchange for being castable on the first turn.
== The Vote ==
There just wasn't enough data to make sure Splexit was the right call two weeks in because the game hadn't settled yet. The game settled, and Splexit was voted to stay permanent.
== The Changelog ==
And finally, the half all of you have been waiting for.
These are the changes that were made for Splexit.
