Designers may have started this plan from hearthstone's mobile phone, and these changes are subtle. Many of the characteristics of the new card can be seen, and perhaps later versions will continue the main theme of these versions.
The quick attack gets faster and faster, and the control deck almost disappears
Fast attack is a routine that Hearthstone has had since ancient times, because of its fast speed, high intensity, and relatively low difficulty of operation, it has won the favor of many players, such as zoo (details are more important) and T7 hunting.
Now T7 Hunt
The control deck restrains the fast attack, and in the environment with more fast attacks, the control deck will also become more, but the current environment seems to have upset this balance. The fastest is not the T7 hunt, now Illidan has reached an outrageous degree, if the hand is relatively smooth, basically can solve the battle at 5 fees, the AOE of the control deck is too late to use it and has exploded, even if it is lucky to recapture the scene, the blood bar is almost bottomed out, and it begins to linger.
Attack Illidan quickly
In this case, the control deck almost disappeared, with the fast production fast is the tone of the Sunken City version, each deck has the means to win, greatly shortening the average match time.
Single-card strengths are becoming more and more outrageous, and specific combinations are no longer needed
With each new version, there will be a particularly outrageous new card, no longer the standard system of 1.5 fees for a card, 334 whiteboards. The Deep Sea Fusion Monster can take a card for 223, or all the attributes of the entourage; the 334 Stinger Boxer can fight the enemy all 1 under the premise of standard stature, or a neutral pirate retinue, white card;
Powerful single card
445 Mocking, the War Roar unleashed the shield of the fierce Onixia Baby Dragon. This kind of easy to obtain, high strength, low fit, simple and easy to understand single card is more and more, there is no need for specific combinations such as weapons plus upgrades and Red Dragon Roar Daddy Collision, so the thinking time and overall time of the game are naturally shortened.
Let go of the passing mechanism, and all classes will be faster
Passing cards are the most important mechanics in Hearthstone, and a deck usually carries several cards with them. In the past, passing cards was not something that every class could easily do, warriors needed the cooperation of the monks of the Temple of Pain, priests needed north counties to cooperate, and hunters were even more miserable, almost never passing the cards.
Unstable passes
But now the card mechanism has been released, and each class has a handy pass. The priest's 332 handmaidens, the warrior's forward battle axe, etc., neutral cards also appear a lot of single cards that find supplementary hand cards, and when the resources that can be played in each round are more and more, the pressure of the scene is getting bigger and bigger, and the end of the game will be faster and faster.
Stabilize the cards
Hearthstone's fast-food approach may not be a bad thing, as hearthstone can be rubbed anytime and anywhere, without restricting the game's players because of game timing issues. Do you like Hearthstone's slow or fast pace?
